You are spot on re: the FAA and it’s Flintstone Standards. Anything that helps safety should be allowed. If you can put it in an experimental you should have it in a Certified Aircraft.
Having said that, The FAA should require the same VFR/IFR rules for Helicopters. Over my 53 years of corporate flying I cannot tell you how many times I have had scary encounters with “RUDE” Helicopter pilots flying around in Fixed wing IFR conditions.
