It is because it goes away in the optional patch 4, since it won't be
needed anymore after that.
Also, it shared the same test with the other 2 workarounds which moved
into their own (one as you suggested is more of a statement of policy
that says, git trusts the developer and doesn't check if --git-dir or
--worktree (or equivalent means to explicitly identify those parts of
your repository) are used.

and the other, was always "special" since it was documented as an
indicator of what to do which could be considered a least privilege
marker as well.

without the optional patch that brings it back, root MUST indicate
through its use of that (or other "workarounds") that he really meant
to access a directory owned by root, and will instead defalt (when
appropriate) to use the id of the user that invoked sudo, which has
(normally) less privilege.

just because I didn't want this to become a bigger change that it was already
indeed I'd been "cutting" it since the very beginning, by first
dropping DOAS support and then avoiding moving things around so it
could be easy to backport.

I think I can provide a version of it that might be able to work with
less restrictions that it currently has, but that would get us into
the "test framework integration" that was specifically punted as well.
