Yeah, the bug report response is a little silly. But the OP's complaint is also a little silly, given that his Vapory library works by writing a temporary scene file, then running the POVRay renderer executable to generate an image file. The same technique can be done with any renderer with a standalone executable, which includes Blender -- you don't need direct access to Blender's internal Python API. In Blender's case, you might need to write a library to author .blend files, which is non-trivial. But it might also be possible to use Blender's .py script files as an ad-hoc scene description format.
