> Generally speaking, I think walletless protocol is needed only when you want to rely a third party to open a offchain smart contract. It could be coinswap, eltoo, or anything similar.
I think a third party would be pointless in general, but then I am strongly against custodiality.
The idea is that you have some kind of hardware wallet or similar "somewhat cold" storage *that you control yourself*, and crate channels for your hot offchain Lightning wallet, without adding more transactions from your somewhat-cold storage to your hot offchain Lightning wallet on the blockchain.
Then you could feed a set of addresses to the hot offchain wallet (addresses your somewhat-cold storage controls) so that when channels are closed, the funds go to your somwhat-cold storage.
I also doubt that any custodial service would want to mess around with deducting funds from what the user input as the desired payment. I have not seen a custodial service that does so (this is not a scientific study; I rarely use custodial services); custodial services will deduct more from your balance than what you send, but will not modify what you send, and will prevent you from sending more than your balance minus the fees they charge for sending onchain.
Even today, custodial services deducting from your sent value (rather than the balance remaining after you send) would be problematic when interacting with merchants (or their payment processors) accepting onchain payments; the merchant would refuse to service a lower value than what it charges and it may be very technically difficult to recover such funds from the merchant.
I expect such a custodial service would quickly lose users, but the world surprises me often.
