Oh, I should have mentioned that as an option, and said that I consider it undesirable. That delete commit effectively forks 'master' history from 'main', meaning there's no way back from the rename. We did this for some of the stable branches in libvirt in the past and I really regret that, we should have just left them idle IMHO.
