The issue here is that it's not *that* simple, once you
start handling all the devices that aren't in sysfs. Moreover,
it breaks the 'load module on device access' model.

Going to a fully dynamic /dev is a paradigm shift, even if you
keep the same device naming model.

Yes, but the raison d'etre of the initscripts or gdm aren't
really 'infinite configurability to whatever policy you want'.
Yet it's a design goal of udev, or at least, it appears to be.
