First, I'd love to get rid of HID_QUIRK_NO_INIT_REPORTS; I am 
whole-heartedly convinced that initializing reports was a big mistake to 
start with, but changing history is hard :)

Regarding hiddev -- there actually are 'legitimate' non-debug users; for 
example NUT (UPS management software) has been using it last time I 
looked. I am pretty sure there are more.

So we'd rather be careful not to break hiddev by default.

I'll think about your RFC a little bit more.

Thanks,
