Pitot/static leak issues when using a "squat switch"

OK so I fly a glider which has nothing in it except a radio and basic instruments. I have an Oudie to keep me out of trouble. I just bought a FLARM brick with ADS-B in. Which I’ll install this winter. I’ll probably install a Trig Transponder next winter with ADS-B out. I’ve installed several different ADS-B out transponder systems in power airplanes.. I haven’t yet installed a squat switch in any of them. Generally power airplanes are faster than gliders. But there’s obviously Cub types that will fly at glider speeds so why don’t they have squat switches. I am just spit balling here. But it’s a good question.
