Maybe I'm misunderstanding, but wouldn't this require comitting to the transaction fees for the various delayed-broadcast transactions (e.g. the Eltoo trigger transaction) because, without a wallet, you can't RBF additional fees by adding additional inputs? Having to set the final fees during setup for a channel that could be open for weeks or months, but which would need to be closed within a relatively short window to prevent fraud, could mean committing to an undesireable high feerate. -Dave
