You cannot XCLASS t3lib_div, exactly because people call it statically,
ergo they will never call your XCLASSed ux_t3lib_div. They call:

	t3lib_div::getUrl()

and not

	$class = t3lib_div::makeInstanceClassName('t3lib_div');
	$class::getUrl();

So it is technically "static" and not extendable, ergo the final is ok
here. It doesn't even have a XCLASS statement.
