Static /dev still exists and works perfectly in servers or embedded
devices.  Recent udev did not removed features (as you are requesting)
and its extras seem to outweight its drawbacks (high boot times).

There is not needed an alternative.  usbfs and the udev/sysfs based
approach coexist nicely.

Which initial comment? That you want to remove a feature to workaround
bugs in an application?

Sorry; you must be subscribed to another maillist than me.  Here, no
article in this thread justifies removal of usbfs with anything else
than the broken VirtualBox.
