Hey [email protected], I am all-in on more, simpler FEPs over monolithic impenetrable FEPs. I take it that points 1 and 2 are due to concerns raised by [email protected] about how OAuth2 properties are already advertised in a standardized manner (I believe per OIDC or similar?) — no objections there. On the topic of scopes, I know [email protected]'s 3b86 (Activity Intents) had some ideas on defining intents that have some parallels to scopes. I don't agree with hardcoding them all into the FEP itself, but I'm interested in exploring how we structure scopes so that they're more straightforward as not quite as fine-grained — a single scope for every ActivityStreams activity type might be a bit of overkill.

That's a really good question, I am not actually aware of any list of software implementing the ActivityPub API. [email protected] and [email protected] may have some leads.
