Is it possible to git clone --filter= without any objects?

[Ciro Santilli <ciro.santilli@xxxxxxxxx>]

At v2.19.0 I was trying to clone a fetch just a single directory:
https://stackoverflow.com/questions/600079/how-do-i-clone-a-subdirectory-only-of-a-git-repository/52269934#52269934

I got really close with:

git clone --depth 1 --no-checkout --filter=blob:none \
  "file://$(pwd)/server_repo" local_repo
cd local_repo
git checkout master -- mydir/

The only missing thing is that uneeded tree objects are still being fetched.

If I had a:

git clone --filter=none

for example then that would be done.

Nothing major since those are small, but just looking for the perfect
command :-)
