Hi David,

As a user this would be an improvement. There are a few downsides though:

1. It creates a new gossip message that can be spammed.
2. It is not easy to figure out whether it worked or not (maybe the person
I had my channel with is offline?).
3. This is incompatible with covert recovery schemes like in [1] whereas
what I propose here builds towards making such schemes possible in the
future.

(3) is also a problem with just doing encrypted backups -- going around
looking for backups means you tell everyone that you are in recovery mode.
