The controller ended (ADR 0590): nothing consumes what nodes report on CONTROL, so the mesh no
longer declares the stream, which would make it again before its removal; MeshConsumers is empty,
the controller's consumers and the events it followed go, and the lease holder's reading
(LeaseHolder, LeaseHandedAway) with them. Only the consumers' names stay, for the removal of the
leftovers and the watchman's read of whether controller still stands. Issue 1126 B3b.
