let's upgrade all public rooms from v1 and spec that all v1 rooms should be frozen henceforth

to stop the residual echos of hotel california ringing in our ears

[turt2live]

possible approaches:

• Put in the spec that v1 rooms do not accept new events anymore
  • Without heuristics to determine if a room was upgraded (as the tombstone can be reset away), we would imply that all rooms are upgraded.
  • Could put a date on it ("no new events after January 1st, 1970 at 00:00:00 UTC")
• Implement a "soft-shutdown" for Synapse/homeservers that does Option A without preventing history from being usable (as shutting down a room blocks all access to the room).
• Option C goes here.

I 100% support this, but the bridge crew would like a heads up so they can start migrating the many many many many many irc rooms still stuck on v1, which have so far been left like that because it's a matrix.org performance nightmare to migrate them at any sort of speed.

I'd strongly prefer to keep read-only access to the rooms without ability to send any new events, ever, with every homeserver generating a block of synthetic events (tombstone, power levels) so that well behaved clients could run business as usual without extra changes.
