Seems you are the first person to offer that explanation. Please
provide a source to back-up that statement as nothing I have read in
the past shows it was developed by anyone for any reason other than
amateur radio.<br>

it was developed by a consortium of Japanese radio mfrs as a
potential digital radio protocol for commercial land mobile
somewhat similar to DMR, and was then offered royalty-free to JARL
for ham use to essentially "beta test" the system under real-world
conditions.

One huge advantage of DMR is that you can achieve 4800 BPS data
transfer in a 12.5 KHz channel or 9600 BPS in a classic 25 KHz
channel (two 12.5KHz DMR channels bonded) for non-voice uses, even
on VHF or UHF.
