Looking at the wing on the GT4, that is a truly functional appliance, (although bit exaggerated for a DD car), its in clean unmolested air.
Just my 2 cents, Ill leave the stock wing on the car when I buy one in 2019, but might change it to a black or carbon fiber one for looks.

Downforce would likely increase if the wing was raised higher like you said, but a wing or spoiler doesn't have to be high up in the air to create downforce. Nascar spoilers are a perfect example of that. They are down on the deck lid and slight changes in rake, height, or width can make or break the handling of the car at the limit. GM increased the front to rear size and the width of the wing to increase downforce for better balance after adding the front splitter.

That article was from Hot Rod, not from GM. Until a reputable GM source comes out to say that "XYZ is going to happen if ABC is done" then I am going to take a magazine article with a grain of salt.
Otherwise what is keeping all of the I4 / V6 Camaro's on the road and stable when they get over 60mph???

I do remember a video somewhere along the way where someone from GM made mention of widening the wing to increase rear downforce. Widening the wing put more of its surface area out in clean air over top of the rear quarter panels.
I don't think anyone said the car would be out of control over 60. Just that at 60 and above, downforce on the wing counters the lift being produced by the body, therefore keeping the rear planted. This is mainly going to show benefits when driving at or near the limit around curves or very high speeds on straights, especially over humps and bumps.
