As I understood in a quick reading, this is aiming at keeping the modem

Phil's paper is from many years ago but the reality is that there was no
further movement away from the legacy AX.25 equipment toward a new
layer, much less toward a completely new protocol.
There is some movement...

OSI or the Internet model? Perhaps not a big question since layers 1
2 are
the same but once we start moving up the stack they differ.
