Comment (by donmhico):

 I have a question. Instead of using regex to check if a string is in
 'serialized-format', why not use PHP's native `unserialize()` to actually
 unserialize the input string and check for its output. From the PHP docs,
 `unserialize()` would return either serialized value or `FALSE` if the
 passed data is not unserializeable.

 See https://www.php.net/manual/en/function.unserialize.php.

 I can create a patch that will use this approach, however I'm not sure if
 there's any particular reason why the WP native function `is_serialized()`
 is using regex. I need some input from others first.
