Meh. Git 3 can still init with the old sha1 hash.

Also GitHub should auto-detect the format on the very first “git push” and handle it then. If they actually require config to be set appropriately during the initial “new repository” dialog that’s just bad ux.

As for this being a looming disaster for industry… it’s inconvenient. And lots of things will break. But we will survive and come out the other side I’m certain. We converted from the Julian calendar to the Gregorian calendar 500 years ago. Surely we can handle this.
