I know, and I'd like then to manually disassociate it :-P

 I don't like the vibe of taking an email address, linking an npub with no future way of controlling, changing or unlinking that info. 

Thumbs down. 

 Exactly why I don’t use it. Not a good idea for your wallet and your npub to know about each other. 

 I 100% agree. 

Problem is (and I'd have to go back to verify this) but I don't think it's obvious that this is a one-and-done decision when you're onboarding.
