UX Idea:

Have clients recognize relay links specifically inside of a comment and insert a small "add" button that automatically puts them in your list after a pop up confirmation (for signing the change and verifying the URI obviously).

Relays for normal people are super confusing, and requiring people to go change explicit settings to have a good experience on nostr is going to turn off a huge number of users, imo.
