Good point.

Eh, I assume nodes using the backup commons would, each time they're
restarted, go through the steps of downloading some number of backups
even if they haven't lost any data. This tests that the backups are
being stored faithfully (essential to any backup process) and provides
cover for cases where a node does lose data.
Thus encrypted backups seem fully compatible to me with covert recovery.
Sorry, I didn't realize that compatibility was one of your design goals
for seed-based peer rediscovery.
