    Is there anything left to do here?

    I might make a fresh tracking issue for external signer integration (hardware wallets, e.g. via HWI). I implemented a rough sketch in https://github.com/Sjors/bitcoin/pull/91. It's a combination of smaller pull requests, some of which should be straight-forward to review, others will require more conceptual discussion (in particular bip388).
