Thanks for all replies, as you correctly deduced, I meant "without
fetching any objects".
The mentioned --filter=tree:0 would basically do what I want it seems,
good to hear!. I wonder why not call it tree:none though to match
blob:none.

Yes, this would be a good CLI API since the since the clone
--no-checkout --filter --filter gets a bit long.
Or maybe:
git clone --lazy URL repo_local
cd repo_local
git checkout commit -- path/within/repo
Or maybe even:
git clene --lazy URL repo_local COMMITISH path/within/repo
to do both in one go.
People are also interested in commit-less directory / file "clones"
