    Considering that the main use of that file that I know about was
    implicit (usbfs is available if its files are present, another
    assumption broken in 2.5), I'm not sure I feel any pain... :-)

    Actually it does more than that ... it tells you what minor numbers
    are assigned to the drivers _currently loaded_ which means that it's
    not really useful the instant someone plugs in another device.

    You can't use it to allocate numbers or tell what /dev/file/name matches
    a given device ... so what is its value, other than providing a limited
    minor number counterpart to /proc/devices? (Which, confusingly, doesn't
    list devices but major numbers.)
