I think this sig, as well as other sigs for super-old platforms will
be valuable not only for spotting fake UA's, but also for alerting
admins to boxes that have been forgotten about for thousands of years
(ok, maybe thousands of days). What are the chances the box that is
actually an Alpha is actually patched? I would personally welcome
more sigs like this for a poor-man's network discovery tool. They
would obviously need some thresholding and maybe should be disabled by
default, but I can definitely see how they could be useful.
