driver and drivers fields should be considered ephemeral?

        "driver": "usbhid",
        "driver_module": "usbhid",
        "drivers": [
          "usbhid"
        ],
        "driver_modules": [
          "usbhid"
        ],

        "driver": "igc",
        "driver_module": "igc",
        "drivers": [
          "igc"
        ],
        "driver_modules": [
          "igc"
        ],

We need drivers for many useful features. Without the drivers field we cannot add the needed block device or graphics drivers to the initrd and we cannot boot NixOS.
In theory this could change over time if the Linux kernel changes its implementation, but this will be also true for any other hardware information that we obtain.
I have not seen significant diverging in factor report output over time.
