In a channelized setting, PIII will not exceed allowed bandwidth. But, to answer your question about why the ARRL pushes PIII; relevance in emergency communications for current sustainability of allotted spectrum. When there is a race for control of long-haul spectrum (for which there is a renewed interest among military, agency and NGOs), it is nice to have a dog in the hunt. But, the move to give more legitimacy to Pactor III (PIII) in the ham bands will fail, as ultimately the Amateur Radio Service's claim to all of the spectrum they currently enjoy.
