Good point. It appears to me that effort spent duplicating UIDIGI
functionality would be better spent coming up with an improved model
that can do things like examine (and, if so desired, limit) the number
of hops traveled by a packet. And I mean do it for real, by some means
other than playing games with aliases to make it drop packets, and be
smart enough to catch and modify W7-7,W7-7,W7-7,W7-7 or other bad
paths.
And since you're targeting the TNC-X daughter board slot, it would be
pretty simple for this new device to be mounted on a different board
and be _the_ digipeater smarts update/ source routing killer that APRS
badly needs.
