I think it’s a great idea.  FWIW, Andy proposed something along these
lines, but the idea was to use shallow clones for tags only because in
other cases it might not work (?):

It got stuck on a minor issue: the patch added a ‘tag’ field to
‘git-reference’, which changed the API, and I suggested making things
slightly differently:

Would you like to see if both patches could be merged?

Thanks,
