Right, but that doesn't mean the server can't support other post types or leave complex UI to other clients. Each server could fallback to displaying a link to an external post at a bare minimum, or display whatever the `content` field. I'm just arguing that the C2S is perfectly viable and would make the fediverse so much richer and more usable. Using the Masto API to federate only specific types with specific software is limiting the fediverse.
