I understand the motivation, but afraid about consequences on the OEM cheap devices that are not always follow letter of the specification.
As per Intel platforms I would look into Baytrail / Cherrytrail devices for the past (I think Hans may help here a lot) and into Elkhart Lake in the present (for the letter I mostly refer to CSRT + DSDT cooperation to get GP DMA devices enumerated, so I _hope_ DSDT shouldn't have _ADR and _HID together).
Hence, from the code perspective Reviewed-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com>
From the practice I would wait for some tests. I will try to find any new information about latest firmware tables on Elkhart Lake machines.
