I know what I am dealing with. It's a security nightmare for those who don't have the network layer understanding like 95% of all Nostr noons. I am not saying it's wrong. What I say is that more tinkering is needed to settle on same defaults that protect the users from the get go.

Agreed. Proper account isolation is crucial for security.
