I believe that both are true and that we'll hardly ever be able to fix the hood bending at very high speeds due to the airflow over the hood.
However, I also think that a great deal of the air causing this phenomenon comes from under the hood.
Think about it: the Toyobaru's engine bay is very well covered; pretty much closed off in comparison to other cars'.
Even my very own Honda was an underbody-slut in comparison, it was just THAT open ^^
Still, at over 160km/h, it felt as if I had a 5k front splitter, functional diffusor and adjustible rear wing installed, which I didn't. So my expectations were kinda high for the BRZ. Well, bummer...
Best way to confirm would be to drive w/o the lower engine bay cover, see what happens. Will enough air be evacuated so the hood will actually bend later in the process of acceleration?
I unfortunately don't have a garage to do that kidn of thing and I'd depreciate that action anyway.

I have another point to reinforce the theory that the engine bay air causes early hood lifts: the flapping.
The continuous stream of air above the hood should create a continuous rise, right? So how does it flap?
First thing that comes to mind: the pressurized air under the hood evacuates through the gaps in the newly-bent hood, relieving the inside pressure momentarily so the hood goes back down, increasing the pressure again and 'round we go...
