From build 3044 the development baton passed to Mark Crossley. Mark has been responsible for all the Builds since. He has made the code available on GitHub. It is Mark's hope that others will join in this development, but at the very least he welcomes your ideas for future developments (see Cumulus MX Development suggestions).
I don't think this is something that is part of the APRS/CWOP protocol. What you see with device is probably something that is only possible for radio transmit broadcasts.
But I'm not 100%. I've just never seen this filled out unless it is coming from a radio. I've tested with various CWOP upload software and none of them affect this device field that you've pointed out.
