Not sure exactly what metric you are referring to for poor performance or in what conditions the mesh would achieve the poor performance you are referring to. As a former lead engineer on a mesh router system, I can assure you that mesh systems are capable of very high performance if done correctly and set up properly. Just about everyone uses them as far as I am aware. You wouldn’t have one wireless access point for a whole massive building.
I thought wifi mesh systems were completely unthinkable in an enterprise environment considering their poor performance.

I’m imagining some kind of massive modified radio tower devoted to supplying wifi to a building directly below
No, you would use multiple access points, wired and likely powered with ethernet.
