Comment (by jonathanbardo):

 It's true that WordPress does have a lot of global functions! I just
 recently started using that function in a plugin and was going to
 duplicate the regex myself and I thought that it would have been useful to
 have a validating function in core since we have a generating function.

 Something I noticed while writing the unit test is that the regex used in
 `class-wp-customize-manager.php` wasn't the same as in the `functions.php`
 unit test and was way more permissive. Any reason for that @westonruter ?
 I think the regex that was in the unit test is the right one for UUID v4.
