I don't quite understand your NACK. The following are measures you say we should take as best practices, which I believe are all implemented: >A) We should accept that users must to backup their multisig account maps >(descriptor with only xpubs) along with their cosigner key material to be abl

Hi Hugo, First of all, thank you for the impressive work on leading the standardization efforts! I believe one ought to more clearly distinguish the "Signer" (as in: one of the parties in the multisig setup), from the "*Signing device*" (which is likely a hardware wallet). BSMS defines a "Signer"
