Well, currently we need this so that Qt runs out of the box on a stock windows installation. This is because stock Windows only supports OpenGL 1.x and we need 2.0 for QML.

In principle yes, but quite some work to get it done. You need to dynamically reroute all GL calls. The main problem here is that applications using Qt often also call into the GL library directly. But it's out of scope for 5.0.
