I don't see any reason this shouldn't be allowed. AFAICT this is only disabled due to the heuristics used to determine whether it makes sense to allow the use of an attribute with `#pragma clang attribute`. This allows libc++ to drop `_LIBCPP_HIDE_FROM_ABI` in a lot of places, making the library significantly easier to read.
