I expect to have confirmation from them that they have got it and
promise to fix the firmware (ACPI tables) for supported and future
products.Can it be achieved? (Note, Hans already told what the HID
should be used there)

The best is to cooperate with Hans as he is much more involved in the
topic of how these sensors are programmed and used in the Linux
kernel. My job here is to fix ACPI HID and
make every stakeholder be aware now and in the future.

Thanks, but let's not be in such a hurry, I really want to hear from
both vendors. I guess a couple of weeks would be a reasonable time to
settle this down.
