My recollection is that automatic configuration of IPMP was on the list
of things to do, but that it never got done.  It just wasn't the focus,
because NWAM was initially designed to handle laptops and other simple
systems, not servers.

What NWAM is supposed to do is configure only one usable interface
(guided by user selection criteria) for the system.  The fact that you
got multiple interfaces configured is indeed an anomaly, and one I can't
explain.  I don't know how you got there in the first place.  It
shouldn't have happened.

Someone with a deeper understanding of the "new" NWAM would have to look
at your system to find out what went wrong.  Unfortunately, I only
remember details about the "old" one ...

That sounds backwards to me.  If a buggy driver exists, then the bugs
should be fixed, or the driver should be discarded.  There's no reason
on Earth to have some other bit of software "warning" users about
someone else's software design failures, whether real or otherwise.  At
best, that other software would just become a repository of uselessly
independent misjudgment -- as new, unknown buggy drivers are written and
old ones are repaired.
