If the compatibility with the existing version were so dramatically
different as Oleg claims, then yes, that would be a basic element of the
replacement project.

Au contraire, we frequently avoid updating the old versions of things we
have in the base precisely because they are not bug-for-bug compatible
with existing behaviors that we count on.

The first question is, where is it not compatible with the existing sort
that's already in the base. The second question is, how well does it
perform vs. the existing sort.

I think those are perfectly reasonable questions to ask, and frankly
they should have been answered before the switch was made. We already
went through this with BSD grep, I hope we can avoid a repeat.
