Instead of leaving an extra output for CPFP, is it not sufficient to just sign all inputs with ANYONECANPAY and expect the sender to make an exact output for the fees input? It would require an extra tx assuming they don't already have a properly sized UTXO handy (which they may!), but I believe CPFP would require that as well. Am I missing something?
I'm a fan of the symmetric delays because it simplifies the game theory analysis, but I don't think the delays need to be the same for both participants (max of `to_self_delay` for both sides), just that the delay is applied equally regardless of who publishes the commitment tx. Like your `to_self_delay` can be what I specify and vice versa, what's the reason for taking the max? -jimpo
