Ah, not so. Well, sometimes, maybe. The fine thread
screws are double-threaded, so they go in twice as fast as
they would otherwise.

No, they are not double-threaded. YOu're thinking of something
else. Coarse is just that; a much coarser thread, more
diameter than a fine, and fewer turns to drive in but I've
never found that to be an issue of any kind.
