Should room name be limited to 255 bytes? #3641

Issue

The spec says the name field in the m.room.name event must not exceed 255 bytes. Synapse, Dendrite, and Conduit do not enforce this over the C-S API. Is the spec wrong or are the servers wrong?

Hm, the horse may have bolted by this point. I'd probably vote to remove the requirement (and later add it in a MSC, if we think it's required). Events are obviously limited to 65k, and any sensible client should be trimming excessive names anyway.
