Ah, but there is no longer any reason for a  directed first
hop anymore under the New n-N Paradigm...

It used to be that we strongly ecnouraged a RELAY or a
WIDE or a NAMED first hop before a WIDEn-N path.
This was because WIDEn-N was not traceable and we
felt the identification of the first-hop by the digi name or
callsign substitution was worth the cost of the extra dupes
that RELAY and WIDE caused.

But now under the New n-N Paradigm, WIDEn-N is fully
traceable and so now we no longer need a FIRST-HOP
to get the 1st digi name identified.  Now just WIDE2-2
will arrive as DIGI1,DIGI2,WIDE2*

AND this now has no disadvantages whatsoever and
perfect dupe elimination.  And, unlike the named-1st-hop
approach, it is still generic and not dependent on any
one digi...

Just a thought.
