TBH, when I was thinking about how to extend hidraw I thought we could have added a new report_type field to struct hidraw_report_descriptor, in order to re-use the HIDIOCGRDESC ioctl handler itself, adding then a HIDIOCSRDESC for setting the report. This looked cleaner to my eyes, but I didn't actually implement this, so I don't know if it was feasible, for instance one problem I didn't investigate further was about the default value of the aforementioned report_type field in order to keep the current behavior of HIDIOCGRDESC.
