Basically this. Not saying the “AUR breaking your system” thing isn’t, well, a thing but I get “error aborting installation” warnings waaaaay more often than my system just outright dying because of an AUR package (which is to say, it’s never actually happened to me).

And usually, when I see that warning, I go “kay, not even gonna bother” because if I ignore it and try to brute force the install…yeah, that potential breakage is on me, not the AUR
