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.
