Judging from the occasional "I tried core.worktree but it does not work in

ugly CVS directories all over the place, it only contaminates my work tree
with a single directory '.git' and nothing else.  Ah, wait --- what's this
core.worktree thing?  Can I get rid of that last one as well?  That sounds
even cooler".

IOW, I do not think it is really _needed_ per-se as a feature, but it was
done because it was thought to be doable, which unfortunately turned out
to involve hair-pulling complexity that the two attempts that led to the
current code still haven't resolved.

I really wish we do not have to worry about that anymore.

Well, as a non-user of this feature, I certainly have no argument
against taking it out. Maybe the subject line will pull some other
people into the discussion.
