Ah, I didn't realize that you want it to be used by some acutal userspace applications. Out of curiosity -- what is the usage pattern you are targetting?
The idea behind debugfs-provided userspace descriptor is that driver developer is easily able to inspect the descriptor, and write a kernel driver that fixes it up in case it is bogus. There were also efforts to make the report descriptor replaceable in a request_firmware() way, but that never converged to state in which it could be applied IIRC.
