are the core developers and other contributors migrating to Forgejo?

Some of them have migrated. I imagine others are taking more of a "wait-and-see" approach.

For what it's worth, Codeberg is quite a major contributor to Gitea as well as the biggest public instance, and they are supporting the fork and will be switching over after the first stable release.

This is my question as well. If the majority migrate then I will follow.
