I don't think that this is correct, because an atomic type may have different size or different alignment constraints. Also the access in general needs to use different low level features of the platform than for a non-atomic access. So in fact that is why an `_Atomic` qualifier should really be seen as a shortcut for an `_Atomic` specifier and it should never be removed.
