right on both counts. (:

One of my earliest confusions using xastir was that I'd see it report
a station on the status line, but not plot it.  It would eventually
show up.  The situation was of course a positionless WX packet
arriving ahead of a position.

IMO this one isn't about implementation difficulty as much as
usability.  A positionless WX packet is useless without other data to
complete it.  This should have never been allowed to exist, but I
assume it's one of those things that some specific piece of hardware
couldn't do, so the protocol was dumbed down to allow it.
