It's not udev, it's other tools making wrong assumptions like that
directories can not be a symlink to a directory, or that a device is
always the same parent device. It's also not udev which fails on newer
installations, it's the lack of information in the non-extensible
deprecated layout which makes all sorts of tools fail. So please
work-off the text from the old help text instead of blaming the wrong
things here. :)
