I don't know how many times this needs to be said and in how
many different ways. If someone decides to use a string that
"looks like" an email address as a login ID, they are free to
use whatever synonyms, mappings, or other "canonicalization"
they like on it.
Then this four-step sequence is okay, right?
1. Site makes signup form that says "enter your email address here".
2. Site does backend processing as it pleases.
3. Site displays the result to other users.
4. Users assume that what's displayed is an email address, and send email.
