Comment:

 @westonruter true, I was triaging a GB report which happened to not only
 enable underscores but also test truthy for underscore domains and I was a
 little TF?

 In fact, I was thinking that we should be filtering input with
 [FILTER_VALIDATE_DOMAIN
 https://www.php.net/manual/en/filter.constants.php#constant.filter-
 validate-domain]

 @manhphucofficial if you want take this.
