@notmandatory, I’m wondering if we should update our signing approach since the current method is deprecated. If we choose to proceed with the update, we will need to add miniscript as a separate dependency, as the version exported from the Wallet (v2.3.0) is 12.3.1. We require at least version 13.0.0. Or should we postpone this update until a later version?

Good question. I've created bitcoindevkit/bdk_wallet#405 to revert the deprecating of the signer mod. The new PSBT signer probably won't be available until bdk_wallet 3.1.
