Which of the activity types:

   - Most of the core formats, still scoping out the feasibility of all of

      - Mastodon doesn’t support quote posts (yet, it’s coming), so we’d
      like to discuss how to model those when we send them outbound.

The consensus so far seems to be FEP-e232:
https://codeberg.org/fediverse/fep/src/branch/main/feps/fep-e232.md .
Evidently that's what Mastodon, Pleroma, Mitra, Misskey, FoundKey, and
streams are doing, among others. More:

FEP-e232 is I think still mostly just Foundkey, Mitra, and Streams.
Mastodon ignores everything, Pleroma did a fix to stop breaking entirely
when encounter Link tags, and Misskey is still using _misskey_quote. The
relevant bit for Foundkey and I think Mitra is that it checks for a Link
with both the correct mediaType and also the correct rel. Foundkey at least
accepts the legacy three property IRIs as rel values, and it authors them
with a rel of https://misskey-hub.net/ns#_misskey_quote
