The linux-hotplug at list is where this should be
discussed, please take it there.

That doc could almost be removed entirely now, as no one should need to
mess with udev rules "by hand" anymore thanks to devtmpfs and the
default udev rules that are in all distros (with one notable exception.)

What is your goal in redoing this?  Why would a user/developer ever need
to mess with udev on their own anymore?

Ideally, it should all "just work" now, and I think it does given your
previous emails about the confusion as to how your driver was
automagically creating the correct device nodes without any help from
you :)
