From my very limited point of view as a user the interop is the major planned feature currently missing in git, and I do not see much point without it. Then again I do not know how useful it will be in practice.

Flipping the default to sha256 would clearly break some things. I can use sha256 repositories in gitea today (no interop whatsoever) but github rejects them.

Then again cloning a repository uses the correct hash which means if I create the repository on the forge and clone it there is no problem whatsoever regardless of hash used. Whill that break as well?

Thanks
