Problem is, while we were trying to nail down the final Grid
Square spec in both the APRS spec and the Kenwoods, I was
finding it very difficult to get consensus.  I never could
figure out who supported what.

I don't think so.  If there is a path from A to B, then there is
not one from B to C.  The probability is vanishingly small, and
since the goal here is to have all these RX's at Igates, then if
the first one heard it, then the APRS-IS heard it.  SO, its
better to not bulk up the packet with the extra 7 bytes.

OK, thanks.  See, I'm screwing up frequencies.. So lets go with
50.62...
Ill add it to the web page until anyone objects.
