That letting any measure of "desirable" legacy spam can performance category (you know, the usual "BE35 and below" macro-class of piston airframes) into the LSA fold will be the death of thousands of children, and that it's pretty unsafe and the FAA should pause and never let that happen. Same reason the primary non-commercial category got snuffed in 2013/2015. I've said it for a decade now, it's always been the OEMs behind the scenes putting their thumb on the scale. They don't want anything to stir up support for the economic life extension of their legacy offerings on the market.
People need to get it through their skulls: OEMs want their legacy non-revenue 20th century piston offerings gone. They want them gone. GAMA, being their resident bootlicker/mouthpiece, is part of that controlled opposition campaign. Meanwhile the perennial ingénues on here keep clicking their heels waiting for MOSAIC Godot to bring them regulatory relief that was never forthcoming. It'd be comical if it weren't so sad to witness.
