I can't realistically imagine the FBOs (fuel providers) at many airports providing a type of fuel only approved for C172s with Lycoming engines. I fly out of Boeing Field (KBFI). Often the FBOs have issues with their fuel trucks or simply don't provide service. You have to taxi to their ramp. The wait can be significant - and that's with just one type of 100LL fuel. Sometimes it's better to fly over to KPWT (Bremerton National), an uncontrolled airport, and use their self service Avgas station with a credit card.

I think the C172-only limitation is clearly interim. GAMI's been burning this in testing for a decade or so. Now, put it into a lot of low-powered trainers. Based on that experience, expand it to other engines and airframes. The end game is an all-models STC; this is an interim step (and a massive one to get the FAA to go from zero-to-one approved models).
