Tangent: IMO this is why you keep your repos under your account, and don't give them over to a group acct. Unless you no longer want/care about control, or things like this happening. If that's the case and you've moved on or are OK with moving on, then do the group account.

I'm large enough environments, it's not really safe to use individual accounts. A hack/takeover while someone's on holidays could take days to resolve. People leaving the project, getting sick, dying would cause havoc on processes and ownership. Once thousands of people depend on your project, you really should move it into an org with others.
