Uses unstable matrix endpoint /_matrix/client/unstable/im.nheko.summary/rooms/{roomId}/summary

[richvdh]

This endpoint appears to be something to do with MSC3266, but that MSC hasn't been accepted, so matrix.to shouldn't be using it.

[richvdh]

more specifically: using it ties matrix.to to homeservers that choose to implement this unspecced endpoint, which is problematic.

It's the only api providing the data the service directly, the service can operate without it by falling back as below. This function acts as a proof of concept the msc needs.

The alternative is to load the full /publicRooms list from the server on every app load but that is not fit for purpose and much heavier on servers. This is what it falls back to if the api is not available.

This alternative lacks the is_space metadata which is why the delight team opted to use this msc in the first place.

Oh, good to know it's only a fallback. Thanks.

(obviously the right solution here is to finish the MSC and use the stable endpoint instead)
