The usual folks (coldcard, seedsigner, ledger, etc) are not seeing the need/maket for it yet.
Not the same use-case as cold storage though. Nostr keys are hot and please make them swappable. Now that I think @zach was working on some cool Frost stuff

would be great! But not for every interaction
It depends on the needs, some folks want it to be in every interaction.
