Not so fast. It was the only way in the USA to allow the
construction of FILL-IN digis using the hundreds of thousands of
existing available TNC's already in hand and not require the use
of a $280 specialized new-N APRS TNC.

Yes, it is slightly better because the length of each packet is
shorter without having to carry the initial WIDE1-1. And it is
the best solution, if people are willing to buy all-new hardware
for fill-in digis. It is good to hear that your country is able
to do this.
We should be able to slowly migrate that direction now that many
innexpensive new-N TNC digipeaters are available. But for
years, users will still have to use the path of WIDE1-1 until
ALL digipeaters are converted if they want the best chance of
