If ground effect is modeled, you can prove with flight testing
and reporting back the numbers. How would you know you're in
ground effect in MSFS?

If you don't know the numbers, and you don't know how to determine
that you're in ground effect in the simulator, then you cannot know
whether it simulates ground effect or not, unless you've read the
code.

Why would the programmers waste valuable CPU time doing
something 99% of simmers don't understand?

Most of the simulation aspect of the product covers areas with which
many of the product's users are unfamiliar. That is the nature of
simulation. You don't leave something out just because a user might
not be aware of it--on the contrary, the idea is to simulate it,
anyway, so that he can discover it.
