#44575 new defect (bug)

Network administrators are allowed to register sites with hyphens, but wpmu_validate_blog_signup disallows hyphens

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.
