Something more sophisticated will happen someday, this is what we have
now.

I'm not saying it does not work, I'm saying I don't want my users to
fool with kernel modules when we know the default should not be HID for
huey right now. If you prefer enhancing the kernel HID driver, and
switching argyll to it, just do it. I don't care as long as I don't have
to maintain workarounds distro-side.
