I forgot one more reason autorouting uucp ! format paths is bad:

Such addresses are path relative. That is, decwrl!amdcad!neptune is
different from ihnp4!neptune. ATT has a machine named neptune, AMD has
a (different) machine named neptune, not advertised to the world. If
some "smart" machine decided to do us a "favor" and change
decwrl!amdcad!neptune to ihnp4!neptune, the mail would end up going to
the wrong place.

I realize having non-unique uucp node names is a problem and
everything should be domainized but there ARE duplicates and
autorouting uucp ! format addresses is a good way to mess things up,
with little benefit.
