What could technichally block this feature ? Federation ?
Yes, we can create a new account or a new channel and transfer each video to the new channel / owner, but we lost all followers for channels and all subcriptions for an account. Plus we can’t group that action for several videos.
Naming URLs can be an issue for creators who change their names (in case of civil state changes if they use their legal name, for example trans/non-binary people are deeply concerned).
I think this is a feature I can try to develop, would you have any advise where I could start ?
