Looking at a 3D object on a 2D monitor is NOT the same as real life. In real life, displays, controls, switches etc are all fixed in one place, and always look the same from position x. This is why a home cockpit will always be more realistic than a 3D cockpit on a 20 foot projector screen, perspective. 3D is great, but not always practical for functionality. I use 3D to fly, and then 2D for overhead, and main panel if i need to read a display more accurately or reach a switch/knob at an awkward angle. Throttle, flaps, spoilers, yoke, radios, MCP, EFIS, and CDU are all taken care of by third party panels/hardware. That is why i think an SDK is a better use of resources than SOME 2D panels, the FS hardware market seems to have boomed in recent years and i feel it is not long before radios and MCP's become as common as the yoke/stick and throttle.
