@maarten @senficon well, OK but what about all those opensource things that were written not from specs but reverse-engineering of proprietary stuff ?
How can I certify that the software I wrote follows the documentation I never had access to, or that this protocol/hardware is devoid of bugs?
Things like ffmpeg, VLC, drivers… how can you certify something you can't verify?
My talk proposal to FOSDEM didn't get through but the subject remains.
