Me, too.

I agree.  I was just making a point that there are ports (esp. for the
-client/-server case, where a slave port is used as the trigger).

Yes, I counted on it :-).  Just kidding, yes this is a problem...but, it
can be solved if the porter adjusts UNIQUENAME accordingly.  However,
I'm not arguing with you: we need a better way.  I'm just offering a
workaround with what we have in the ports tree _now_.  And, as you say
below, adjusting UNIQUENAME is akin to having to add CONFLICTS.  Please
send-pr your patch when it's ready.  Thanks.
