I mean, feel free to try it out and if it happens to work I guess there's no harm in offering the option. I just think I recall there were more issues with clang, maybe things have changed now. We sometimes have to rely on some pretty specific GCC extensions to make things work well the way we need them, and while I think clang is compatible to most of those, if there are cases where it isn't I'd rather stick to being GCC only than have to resort to inferior solutions to allow clang support.
