It is infacto a small spoiler in itself, like before windscreen if the rake is not correct.
Air transition around object with as little disruption as possible.

So that begs the question if it simulates a small spoiler, why not just have a small spoiler.
I can see that they may be beneficial in specific circumstances, bu the fact that they create drag to hopefully reduce drag makes it very hard to get setup right.
A bit like the bulb infront of large ships, it works fantastic at a specific speed because the wavelength lines up and they reduce drag, but at any other speed the drag is increased.
