This is almost, kinda, sorta what NIP-28 Delegation was supposed to be we've since moved away from that it seems and are now just using Pablo's nsecBunker.

I’ve yet to figure out nsec bunker. You using it?
I teared it once but haven't made the jump to use it for everything, yet.
It took a bit to wrap my head around it but it’s super powerful. Use make a throwaway admin key and put your real keys in the bunker. Then you can rotate the admin key all you want and keep your real key at home.
I experienced inconsistency getting it to work very early on and haven’t been on nostr much outside of Damus lately, but I’ve been meaning to reinstall nsecBunker.
I set it up a month or so ago but only place I could find to use it was Coracle at the time. I logged in the other day but it wasn't able to reach my bunker. It's on my to-do list to get working again now that Spring is supporting it.
This is correct
