In spite of this the repo remains at 3.0G. Though now there are a bunch lines like 

warning: reflog of 'refs/notes/commits' references pruned commits
warning: reflog of 'refs/remotes/origin/main' references pruned commits
warning: reflog of 'refs/remotes/origin/releng/11.0' references pruned commits

in gc.log. I fixed that with

git reflog expire --all --stale-fix

I just did

git remote set-url origin <new url> -- this really only rewrites the url= line in config!
