i'm honestly really excited for gitlab's activitypub support they're working on
https://docs.gitlab.com/ee/architecture/blueprints/activity_pub/index.html
especially the cross-instance collaboration (with issues & **pull requests** being from other servers ‼️ )
https://gitlab.com/gitlab-org/gitlab/-/issues/423245
As noted in a couple places they're also going to be leveraging ForgeFed, which is a major plus, with hopes of it being compatible with Gitea's inplementation
