Is it possible to create a gh command alias to blobless clone?
gh alias set clone 'repo clone -- --filter=blob:none doesn't work because gh only accepts repo URL before the --.

I was able to, weirdly, set in .gitconfig:

[alias]
  bclone = clone --filter=blob:none

and then:

gh repo bclone org/repo

does seem to work?

But I swear there have been times when it didn't...

The alias did not work for me. It does work, of course, as git bclone ...
