remyers on Nostr: I would expect multi-party channels that include end user nodes to update less ...

I would expect multi-party channels that include end user nodes to update less frequently than multi-party channels between routing nodes. But a 2 of 2 channel that settles to a multi-party channel could update whenever both parties are online - even when the other multi-party signers are offline.

If updating the multi-party channel isn't possible, then you have to go onchain.

How do you splice out a particular channel party that isn't responding in a fair/safe/fee efficient way? That's what seems to be where more work is needed.

Is this a solved problem with other covenant schemes? I think they all could use more detailed investigation.
