Seems like a great feature for a satellite / broadcast feed where the main constraint on keyint is latency and channel switch time. Having slight wiggle room is probably acceptable in those cases.
So, --keint 50 --gop-lookahead 25 would still have a max GOP duration of 50 frames, but the average would tend to be closer to 50 than 75?

Seems worthy of some testing.
