Oof yea channel management is tricky. I've been meaning to try an Alby Hub + phoenixd combo to get around this. I think @bumi and they have been trying to get folks to help package this for umbrel/start9 etc and Raspiblitz may already have it (cc @openoms?)

Also, what about cashu options like @Minibits? They're not self-custodial, but there's pretty good privacy guarantees for small amounts, and you can sweeping to self-custody once your balance gets to a certain level
