I am slightly confused about:

N4266: Attributes for namespaces and enumerators

Example:

enum {
old_val
#if __cpp_enumerator_attributes
[[deprecated]]
#endif
, new_val };

The notion of feature testing macros for C++ attributes was not voted
favorably by EWG in Kona, and what I understand from reading the
discussion (which could be me horribly misunderstanding the feeling in
the room) was that there was insufficient motivation for such a thing.
However, this is a feature testing macro... for an attribute, just
with a different spelling than what SG-10 proposed.

If we need this feature testing macro (which I believe we do), can we
use this as a motivating case for EWG to reconsider as to why
__has_cpp_attribute is valuable?
