We already have them even without this case. I hate this too. I would
love to just get rid of *all* the others, provide a single
implementation based on ksh93 that offers all the most often requested
features. But that's not this case.

If you feel that way, then either don't use ksh93, or use a .profile
that disables the builtins.
The point of this case is that the builtins are drop-in compatible. You
should not care about the implementation. If you *do*, then you're an
edge case user and its not unreasonable that you have to suffer some
extra pain to get exactly the implementation bits you want.
