Py-Videocore: Python Library for GPGPU on Raspberry Pi

All the GPGPU projects on the Pi seem to be centered around low level assembly language for the Videocore. Are there any technical reasons why there are no higher level C/C++ abstractions?

In the requirements it says Python 2.7, does it mean 2.7.x (hence no python 3 support) or "2.7 or newer" (hence with python 3 support)?

Cool project. Small rant; can we please stop titling our libraries with the language extension as a portion?
