I think this is less about source code itself, and more about the surrounding ecosystem of project management. Handling of issues, pull requests, who gets commit or admin access, all that stuff. If you mirror your git repo to other providers, fine. But if you have thousands of issues and PRs on Github, you still can't really move away and you still can't really work if Github is down.

Edit: I absolutely support federated forges, including Tangled as well as ActivityPub based approaches like the (slow) progress to federate Forgejo.
