Would be curious what kind of validation the user can actually do with greenlight if they don't connect to the bitcoin network. Also, if your auto-signer goes offline, it seems like you have the same problems of not running your own node.

I like the idea of VLS protocol for being able to physically separate your keys from your node, but when you are are using someone else's computer for your node, that's where things seem to break down.

What's your weakest definition of a self custodial lightning wallet?

I'm actually not completely sure about that. I think the greenlight server provides some sorts of compressed proofs about the the transactions, but I don't know how it works exactly.
