One of the biggest short comes of nostr design is the privacy trades offs.
Specially because clients dont offer ways to treat nsecs as disposable artifacts.
Or at least create BIP85 style derived nsecs from a master nsec.
The way we are using and designing it, it's a gift to the big brother :/
We need a standard for backup/migration of user space of wallets, specially those with multiple wallets/keys
Like COLDCARD Teleport
Make it super easy and secure for users to migrate all their stuff, keys, descriptors/paths, labels, etc... between wallet vendors
Specially on phone apps!
