Fully agreed, but I don't see anyone suggesting such hostilities. You
can continue shipping the old spellings,
and we all can, and we can still do the policy-fixes in the standard,
and no user will be hurt the slightest.
That's what I mean by not seeing a convincing argument to deviate from
the policy; renaming
__cpp_lib_array_constexpr doesn't in any way prevent you from
continuing to ship that macro spelling.
