For people who have experience with game development: how hard is it to implement deadzone settings?

I'm asking because the game has been out for a while yet we still don't have deadzone options. For a fps game where accuracy when shooting is the most important thing, that sure is strange.

The deadzones for the left stick are way too low and people, including myself have drift issues.

The right stick is also weird when it comes to aiming. Having options for modifying the deadzones as we see fit would improve the gunplay a lot!

If you're a dev, or you know about fame development, please answer this question.

It's getting pretty frustrating.
