There is a new thing out there... it's called evolution
Mixes are for reducing workload, and making your flying even better, maneuvers more precise. Of course, if you have no intentions doing so - by all means leave the mixes off...
Fair enough, I guess there are some who like to simply point their plane around the sky and some that want to "fly" it -- which means dealing with its imperfections and things such as turbulence.
Do you use gyros for hovering?
Of course (or at least I hope) not. However, using your rationale, why bother to learn to hover properly when you could just use some technology to make it easier?
...like driving a car with a steering that needs aligment, but hey.. "I can just correct it by turning the steering wheel an inch to the left - makes me a much better driver anyway"
That was my point -- if your plane pulls or pushes during KE, you really ought to either trim it out properly, get a better plane, or just practise until you can fly it on the sticks.
