But I see no reason for the FAA to be involved in the matter.

Other than some quirks in how you start them, I can't think of anything
you really need to know about fuel injection to safely fly a fuel
injected airplane. Certainly nothing that couldn't be taught in a
couple of minutes (i.e. "there's no carb heat").

Supercharging is a bit more complicated. You can get into trouble
and/or damage the airplane, if you don't know how the system works.

A much steeper learning curve is mastering the current crop of avionics.
Somebody who did their instrument training with 2 NAV/COMs and an ADF
can get themselves into a world of hurt if they launch into IMC with a
modern GPS and think they can figure it out as they go. I guess the FAA
figures people are smart enough to not do that.
