But you are overlooking the big fact that a single user of WIDE2-2
is only adding QRM to his local area and one hop beyond.  But an
HF user of GATE,WIDE2-2 is adding his packets to DOZENS of
VHF networks all over the country.  This is bad for two reasons.

1) It is out of area QRM to all those users and you could be
thousands of  miles away.

2) Since it is coming into their local area from a GATE that can be
two hops away, they are POWERLESS to contact the GATE operator
if such QRM is causing unwanted interference.

Whereas if all HF==> VHF gated traffic uses the ORIGINAL 
receommended path since 1994 of VIA GATE,WIDE1-1, then
wherever that QRM lands, it is never more than 1 hop from the
source and the locals can resolve the problem at the local
level with a simple voice call to "ole' joe" the local GATE operator.

We must make this point clear in all of APRS.  That is, that  it is
just not fair to the APRS network to inject out-of-area-packets
into anything except the local network, so that it remains under
LOCAL control.  And 2 hops is NOT local.
