2. We should change it in libx264 and libx265
Changing it in nvenc now would be kind of an API break, as the behaviour
might change without someone expecting it.

I don't think so, onlything is changed is when you forcing keyframes
with -forced_keyframes option it was not working in NVENC without
specifiing -force_idr 0 or 1, is there any other situation when some
parts of ffmpeg will force key frames and NVENC naturaly ignore them?
It's primarily a concern with API users which might set the pict_type.
Probably does not affect any notable amount of users.
Might as well remove -1 as a supported value from the option then.

I checked libx264 and there is -1 option, so i think it should stay
there also for future use (like automatic IDR/INTRA decisions). But it
could be removed also.
