UX: username is not mentioned in the verification email
Created by: unknwon
Bob could add Alice's email address and send out a verification email to Alice, but Alice won't be able to verify with the link because the link knows it was generated for Bob. Then, it is super confusing for Alice what is going on.
If the email mentions the username "Bob", Alice could have known this email is a mistake and should not even try to click on the link.
