In my experience scripts that expect your remote to be a certain way will break with this approach.

I don't really use a lot of script that wraps git; but so far the two things I do use---lazygit and github cli---don't have problems with this approach. Github CLI can identify the correct corresponding repo on Github, and also can choose the right user account associated with this repo if there are more than one authenticated user.

I mean, it seems to me that any script that tries to do something with git remote URL, should deal with any string that git thinks is a valid remote URL. `ssh-host-name:owner/repo` is not exactly an edge case.
