Probably not.
I can change it over to mirror the official repro. But since we will have an official Github mirror, what's the point?
And it will be a "forced update" breaking all.
Our new git has new hashes. So if I continue my mirror, the next fetch/pull will do a complete new clone (and you will have double the date on your disk, my hashes, and the new ones).
You will need to reset all your branches, and do major clean out work.
