Nothing has been moved. The architecture was always set up like this (see statements about how uninteresting the ARM side code was). Sure it's disappointing but it doesn't limit the educational drivers for the project as most kids won't be learning basic programming with a highly specialised vectorised graphics processor.
The architecture is a little weird because the SoC they are using was originally developed as a graphics co-processor for mobile phones. The ARM core was originally intended purely for debugging the GPU. However the architecture is what it is and the choice of SoC is what allows the foundation to get to their price point.
I'm sorry if this education foundations product doesn't meet your requirements but there are plenty of other more expensive boards you are welcome to use if you want to get into the GPU side of things.
