Well all could switch to intrinics or none would is also on the table. I wouldn't be opposed to either as well, what truly matters for me is the headers part and another approach can be used than intrinsics (actually I can keep the clang builtin and lower them to the GV, I previously made the mental shortcut no intrinsics = intrinsics/builtins).
