Why?

Supposedly this is the Coanda effect at work, but there remains considerable
debate about this.

There isn't any debate about what a wing stall is, and what causes
it. It has been well-explored in wind tunnel testing. The phenomenon
of wing stall is real-world evidence that the top surface of the wing
is a large contributor to lift. The Bernoulli effect and the
associated Coanda effect are well-understood scientific phenomena.
They explain how the curved top surface of the wing displaces air
downward. Unless someone can come up with a better explanation for
the fact that wing stall destroys lift, I think the only debate is by
people who are determined to ignore the scientific evidence.
