We need to test first that /room_summary API is working on m.org.

Does not look like it's enabled https://matrix-client.matrix.org/_matrix/client/versions

Nevermind, it works just fine https://matrix-client.matrix.org/_matrix/client/unstable/im.nheko.summary/rooms/!amwlFMejXQcoCxNYHH:matrix.org/summary

Okay, I have finally figure out what's happening

• the room summary API is indeed enabled on matrix.org and working fine for most rooms
• it is not however capable of giving us data about non-joined + private rooms
• the SDK addresses that by first trying to use known rooms before resorting to the preview endpoint
• that fails if it's a brand new room that the client doesn't know about yet i.e. a sync hasn't ran, which is exactly what's happening here
