That isn't wholesale, it only replaces the OS on the ARM processor of the modem, the OS on the Hexagon processor of the modem handles radio stuff and lots of the layers of LTE.

That would, I expect, help with the unfortunately old kernel version and generally give greater confidence in what's running on the second computer inside the computer.
