For example, if I were to 'git clone' a project currently on gitlab, create a github repo for it, add that origin, and push... Well, that pushes commits authored by every single person who ever committed to that other repository. Do I have to make all of them re-push only their own commits in order? Can robots not mirror repositories anymore? What about commits authored by people without github accounts?
There's also the obvious issues of me merging a coworker's commit into my branch, or cherry-picking, or rebasing a third-party contributor's commits to update them before merge.
I think the case of "push an existing repo with N authors to a new repo" is a really compelling reason though for why that sort of "you can only push commits with your email" thing would not work.
