  | It's easy to generate the equivalent 
  | of %s with sprintf on the corresponding time_t value,

That's true for C code, %s is mostly used with date +%s which doesn't
need the modified strftime_*() functions (though I don't believe there's
a standard PRIxxx macro for time_t).

  | If I understand things correctly, it's impossible for an implementation 
  | to conform to both POSIX-2017 and draft next POSIX in this area.

What do you believe the problem to be?   I don't believe there was
any intent to change things (beyond adding the new tm_ fields), and
if something slipped in by accident it might not be too late to fix it.
