Speaking of versions, I've triggered an error on a remote host (with 
Tramp) because it had older Git installed.

It was running a Trisquel 9.0, which is pretty old, but looking at 
https://repology.org/project/git/versions it appears even the latest 
Trisquel (11.0) only uses Git 2.34. Same for Ubuntu 22.04 which it's 
based on, both officially supported until 2027.

The attached makes detected version connection-local, that's step 1 (*).

It could use some review, though. There aren't many examples of doing 
that in Emacs code.

Michael, could you take a look? Does this look reasonable? Should 
:application be 'tramp' or 'vc-git'? Is the 
'connection-local-set-profiles' call needed here at all or can be skipped?

(*) Step 2 might be to limit the --sparse argument to Emacs 31 and 
newer. :-/
