I know an older thread, but add another use case. I built an OBDII front end for my vehicle data with Arduino/Canbus/Modbus TCP. Works great, but having it timeout on the touchscreen in the vehicle is a bit of a pain, and don’t particularly want to be tethered to using a hotspot connection every time I’m in the vehicle.
I hope you aren't holding your breath. Maker is free. Turning it into a untethered license would spawn egregious abuse.
I’m sure it probably would….I’m guessing with a periodic internet connection, some metrics could be collected, although IA has said it’s not monitored, to expose abuse, so I understand the thought process. But one can always dream 
FWIW, I made a custom roof mount on my Suburban to hold and power my Starlink Mini. That would maintain your Maker connection pretty well, I think.
