 As a network administrator, I can register a site with a hyphen in the URL
 from `/wp-admin/network/site-new.php` (see here:
 https://github.com/WordPress/WordPress/blob/master/wp-admin/network/site-
 new.php#L237). The guide text says:

 > Only lowercase letters (a-z), numbers, and hyphens are allowed.

 However, as a user on `wp-signup.php`, I can only use lowercase letters
 and numbers and this is enforced by `wpmu_validate_blog_signup()` (see
 here: https://github.com/WordPress/WordPress/blob/master/wp-admin/network
 /site-new.php#L237). The error message says:

 > Site names can only contain lowercase letters (a-z) and numbers.

 Is there a reason for this discrepancy? As a network admin, it means that
 I have different URL options depending on where I register a site, which
 is counterintuitive. Ideally the same URL options would be available for
 site registration wherever it happens.
