Let's say you have two emails A, and B.
Your primary email is A, and you have kept your emails private. So you use the noreply GitHub email for commits in git and online, and it blocks command line pushes which expose my email.
I would like to continue that, but I also want to show email B on my profile (that is, in the email field, not in the description). But I do not want to inadvertantly leak A.
Is this possible?
