It is working fine with ordinary ACPI devices providing a HID.

That's an implementation detail. We shouldn't be making recommendations
to vendors based on Linux shortcomings.

as long as they're willing to document their
implementation.
I'll point that out, something like:
If you really have to use WMI for Windows compatibility reason, make
sure the important parts (is there already something to mention?
Against what is the driver loaded -> autoloading?) are documented well.

There's no valid reason to suggest that vendors use an entirely custom
solution over using WMI. In some ways, reverse engineering is easier -
we can see all the entry points. But yes, vendors who want to support
Linux should document their firmware interfaces.
