I bought a Mavic Mini as a "casual" complement to the "serious" P3P. Is there any advantage to voluntarily registering the Mini? (Aside from if, for some reason, I use it commercially, in which case it would have to registered. Or if I add prop guards, which brings it above 250g.) The only reason I can think of is that it might indicate positive intent to follow regulations, but otherwise it just seems like more gub'mint stuff I don't need.
