Yes, AP has the mechanisms to support it, and I think the specific vocabulary is largely agreed on (there's a FEP, not sure where it is in the process).
It's frustrating that the perception of AP, and current reality of most AP-based software, is so shaped by Mastodon's specific implementation. On the one hand Mastodon's adoption was key to the success of AP, but on the other hand Mastodon's specific choices (also including not adopting C2S) have been less than helpful. Oh well, it is what it is, and hopefully thanks are changing (both with Mastodon and with the broader fediverse)
