Comment (by TimothyBlynJacobs):

 Does that line actually get executed? It looks like it prefers regex which
 I think needs to be available to run WP?

 > The idea is to just remove character that are not valid in an email.

 Right, what I'm trying to figure out, is if there is a case where the
 sanitization would not allow an email that would have previously been
 allowed by `is_email()`. I understand `filter_var` doesn't do the complex
 checking `is_email` does. But I'm wondering if any of the characters it
 strips would've been allowed by `is_email`.
