The three nvenc encoders already have different ranges on those values.
And making the range of the global parameters biggers might have 
implications on other things using them, which now might get values that 
are out of range. So that'd need to be checked individually in every 
encoder now.
So I'm not sure if it's really less or even more work to go that route.
