Is this NIP-26? Or similar? Delegation was deprecated two years ago, but I welcome additional exploration here. I want delegation. The problem is getting all clients to support it. Frosty was doing something similar, but was compatible with all clients using it's own NIP-07 and NIP-46 signers. I'd love more info to read up and explore when I return.
