We still have not settled on this..

This is tightly related to the ceremony and the setup.

After discussion IRL with @JSwambo and @kloaec , the process the more aligned with a decent UX for stakeholders and futures extensions of the protocol (watchtower rental) is to:

Add a "change policy" tab to the GUI (cc @edouardparis )
Get a policy configuration file out of a nice interface (checkboxes?)
Sign this file using the Bitcoin HM (this assumes to be able to read the content of the file on the HM screen) and probably a custom pk (maybe m/0/0/)
Send it through the Noise KK channel with the watchtower
The WT verifies the signature (since it has the xpub) and changes its policy on-the-fly

Marking as settled as it seems to be the best solution but needs some re-hashing imo

revault / practical-revault
