Correct! The spec IS for an identifier. It's not verification. People are confusing the two. That's fine, normally a check mark means verification social networking platforms.
For example: There could be 10,000 billybob accounts on nostr, but only one will ever be billybob@nostrplebs.com.
This isn't verifying that billybob from nostrplebs is the "real billybob". It's identifying that one of the billybob's out there is from nostrplebs. That's it.
