Of course, you can always use a loopback address as the 'unnumbered' address,
which gets around the problems of the ethernet availability.
Obviously the loopback interface uses an address itself, but depending on
whether you're using a loopback interface anyway, and how many unnumbered
interfaces refer to it, unnumbered with a loopback can still save IP addresses.

Subject: Re: IP Unnumbered.
There is one huge disadvantage. If the ether segment goes down in an ip
unnumbered setup, then even if everything is physically ok on the serial
link associated, that serial link will become unusable. From a monitoring
perspective, unnumbered is a bad idea. I suspect some people use it to
save ip space.
