Last, is the scenario you mentioned. If you are doing a non FMS based approach, you could be in this scenario. Though it's not often, I have seen certain approaches removed from the database. For example, Honeywell will remove approaches from the DB if there's an error or if the FMS directs a right turn when it should have been a left, etc. I have also been to places where the airport did not exist in the database. Maybe you are old school and just want to practice and fly that LOC only approach in V/S. You calculate your timing and descent rate on approach anyway, now you just have to dial in your estimate and adjust as needed.

Oooo, I also forgot PAR and ASR approaches, great candidates for V/S.

Is VNAV actually used by RL pilots? I mean descent is dictated by ATC so whats the point of VNAV?

Have a peek at flightdecktosim's approach tutorials. He uses a mix-match (mish mash?) of various methods. https://tinyurl.com/2p9e9wrp

What alternative would you recommend? 

I use Pilot2ATC now and again - see my fascinating lopsided head avatar.
