In games these categories of audio are calculated and mixed locally in real time, for movies they are mixed down to a single track and compressed ahead of time.
These days having three audio tracks would not be a significant problem, compared to the high resolution video track. But I guess the industry never changed.

video
environment audio
effects audio
vocal audio
environment audio are things in the background like cars, birds, children playing.
effects audio are sound effects like breaking glass, car crashes, explosions.
vocal audio is just that, the dialog between characters.
streams MUX these together into a playable movie on the fly and is how it’s possible for them to use the same movie with different language dubs.
it’s completely in the realm of possibility for them to create a control to manage the volume of each of these layers before muxing. that would break their caching strategy though.
physical media like Bluray should be able to do it though. BD players never implemented such a feature that I am aware of.
You can record multiple channels, you already have left and right recorded separately. Other channels could exist for different things, it would just need a standard to follow to be useful
