Comment (by stevegrunwell):

 Fair point, patch has been updated to use the current regex pattern.

 As far as core never using `filter_var()` that's ''technically'' true, but
 I did find one instance in wp-includes/class-phpmailer.php (which is why I
 was like "okay, cool, let's use `filter_var()`"). I've yet to come across
 a system with the filters disabled, but that doesn't mean they're not out
 there :)
