Yeah, the tradeoffs seem to be "add various gentoo/arch support to llvm" vs "nobody should use llvm for anything popular, because gentoo can't use it on abnormal architectures" Put some of this upset-energy into building out gentoo+llvm. There's no way you're going to convince the entire programming world to stop using llvm at this point, even if you claim it's reasonable.
