Like a specification[^0], which is exactly what ActivityPub is and what federation in Forgejo is built around?

I'm sure that sentry and co could spend a few bucks and commit a KPI in one of their upcoming quarters to figure out the activity pub spec and support integrating with it if their hearts desired. It's a chicken egg problem and we all know chickens exist. It's clear that the centralized model is getting left behind, especially as the EU is moving away from US services and they continue to invest in open source, European-based alternatives like Codeberg and Forgejo.
