I think it's a reasonable feature to have. I don't recall seeing anybody
else work on it recently (and a quick search of the list archive
confirms).

But see below.

Yes, that is the tricky part. :) There were some patches in 2024:

  https://lore.kernel.org/git/20240307205006.467443-1-ignacio@iencinas.com/

where the issue came up. Based on my recollection and a quick skim of
the thread, I think the consensus was that it's OK to document that it
is system-dependent whether we'll match against a short of fully
qualified hostname. But exposing our view of the hostname via git-var
(e.g., "git var GIT_HOSTNAME") might be a helpful debugging aid.

It looks like after review on v3 of the series we never saw more. I'd
guess the author (cc'd) just never got around to pushing it forward.
