I think the absolutely least understood feature of ActivityPub is `proxyUrl`.

This is the feature that lets you ask your ActivityPub server to fetch AP objects from other servers on your behalf, using your identity.

This is what lets you get private or followers-only content from other servers.

Every. Single. AP. Server. should. implement. `proxyUrl`.
