Agreed! It would be nice to check all of them. Even checking for
`attribute` and `__attribute__` could be potentially reasonable (i.e.
so that people are reminded to consider adding whatever attributes
they need into `compiler_attributes.h`), although perhaps too
annoying/noisy for some (e.g. for `arch/*` devs...).

Cheers,
