Well, you're essentially describing a fly by wire aircraft. Inherently when the stick is returned to center it should not roll further at all - if it does so, it loses precision and is generally considered a relatively failed design. In a crosswind, etc, you absolutely do not want the airplane trying to smooth your inputs, not when you're trying to decrab and align, etc, just for "feel of inertial" - The difference here is that the Airbus stick is a heavily damped unit in reality. Your return to center from your desktop joystick to a real Airbus sidestick is probably "lighter" by a factor of 10, if not more. However, we cannot slow down your return to center artificially, nor rate limit it - as we cannot decipher whether it is a return to center, or left through right. The rate limits of the roll channel at 15 degrees/s are respected regardless of course, but you can get to it, and out of it, very quickly with a lighter joystick - so what is the solution?

Well, a good calibration would go a long way to begin with - going to the sensitivity menu and starting to adjust things like reactivity to your liking - and similarly with the actual input curves, we have basic recommendations as a starting point on our knowledge base - but they are simply a starting point - you need to adjust to your liking and add and remove weight as you see fit by modulating the curve. It will also add "inertia" in the sense your return to center will take longer, so there is an emulation of damping if you're able to mix reactivity and sensitivty curves. It would be specific to your hardware and your own taste - something we unfortunately accomodate (the hardware that is - there are 10s of thousands of combinations here..) - all we can do on our side is to make absolutely sure the fly by wire does what it is expected to do per it's design - as any filtering we add with naturally turn things out of sync on other joysticks. Things like SDS etc are present in options to also help with this. 

Re flare - yes, that is exactly again the system working as intended and as designed. Your flare "weighting" is dynamic, the nose down input is "dynamic", and based on the actual mathematics that utilise your pitch angle through 50ft as a significant input - more pitch means, in laymans terms, you're gonna feel like you need to apply more backstick, and with less pitch, you feel like you need to apply less. As it would be in a conventional aircraft in a sense, but here we and Airbus are adding the impetus. If you are destabilised in this area you're going to have an issue unless you're familiar enough with the aircraft that you are in sync with it's attitude coming in and how much backstick to expect to need based on where you were at, at 50ft. Generally, it works out in reality because the pitch attitude at 50ft is not going to be far from the expected design norms where in sim.. well, as you approach at the wrong angle, it's gonna bite if you're not used to it.

And yes, we continue to work on it. It has been promised, it will be delivered.

Oh YES, Thank you very much for that clarification!

I'm trying to describe an about 60k kg aircraft, that cannot manouver abruptly or flying on the rails, generally speaking. I know that an A320 needs to be flied on fingertips, and I use my fingertips to fly it properly without changing the default settings of my joystick, because I love to feel how an airplane flies with the default joystick settings. Your joystick workaround works well, but it is subjective, because it can mitigate the "rolling on rails" or the "lack of inertia", but the problem is still there because it seems that your airplane stops a bit abruptly when the joystick returns to the center after rolling. And this has nothing to do with the flybywire system, nothing but the normal physics of a 60k kg airplane, and I know that the MSFS20 environment doesn't help on this aspect.

Regarding the flare, if I'm at 50/30ft landing on the runway and I pull back the throttles at about 130kts in a "retard" situation, I'm expecting that pulling back the joystick to raise the angle a bit, a 60k kg airplane will stall sitting on the main gear. This is not a standard landing asset, because the A320 with the landing flaps out, the nose doesn't have to be raised so much, but just in case I'm expecting a good stall if want raise the nose for any reason, without enter in the alpha limit range. But I need more testing on this aspect.

But fly by wire is exactly doing this: Counteracting inertia. Fly by wire would be a chore if you had to adjust and counteradjust and wiggle the sidestick back and forth; ironically this is a pattern many pilots learn early in their flying days and still show while manually flying an Airbus with fly by wire, leading to pilot induced oscillations.

Have you flown the F18 on DCS by any chance? It has fly by wire and it stops the joystick movement on a dime.

For transparency: I'm a community mentor at the BATC discord. However, I do not get paid for it in any way.

I have flown that and many other simmed airplanes, you can't compare the wings and ailerons surfaces with those of a 60k kg airplane like an A320. I have been many times on the A320 as a passenger, and never had that strange "stop/rail perception" while rolling, the inertia thing allows a more comfortable flight, and you can feel that with bigger airplane like a 747 and A380. But I think to be an open minded person, let's see what happens in the future with FS2024.
