This is a request to add a hook to the function User::isValidPassword so that extensions can impose additional password requirements. The new function would look something like this:

static function isValidPassword( $password ) {

global $wgMinimalPasswordLength;

return (strlen( $password ) >= $wgMinimalPasswordLength) && wfRunHooks( 'User::IsValidPassword', array( &$password ) );
}
