We should generate sensible default names for rooms serverside rather than relying on clients to get it right. (SYN-265)

[matrixbot]

Currently if a room has no explicit name (e.g. Matrix HQ) it's up to the client to synthesise one by looking at the membership list, etc. This is not ideal, because:

• It means we have to xfer the whole membership list just to display the Recents index
• It means clients have to get the logic right, and be consistent across multiple different implementations (which currently we fail abjectly at).

So let's do it serverside instead. We can even internationalise it if needed

This would be the implementation of matrix-org/matrix-spec-proposals#688

going to keep discussion on this over at matrix-org/matrix-spec-proposals#688

[richvdh]

matrix-org/matrix-spec-proposals#688 was the spec issue tracking this, and it got resolved via the room summary. It's surprisingly hard to do better than that, and if we ever wanted to, it would be primarily a spec issue, so I'm going to consider this resolved.
