> if the challenge of knowing what Fediverse Apps implement which bit of the spec is a blocker, is there a standard way to declare which bits of the spec an app is conformant in?
The #ActivityPub #FEP process keeps a list of implementations, in each of its documents. The FEDERATION.md was once introduced as "something to start with before going more complex wrt introspection", a temporary bandaid to bring improvement. Its adoption and use, and later its description as a recommended practice are going very slow though. Still, a very useful practice, compared to lacking such doc and perusing foreign codebases for the info.

That might be a good solution. For part of a much bigger problem. No #funding bakes bread yet.
I addressed this with @nlnet in the past, and intend to bring it up again next week.
