Nice sheme - this will even allow to check the software paths
by just tuning the GL version (e.g. via environment variable).

But what will you do if your software path is not yet covered
by a specific OpenGL version but you still want to use it for
testing your experimental application?

It doesn't help us much with that case, it's true. However we don't have that capability with the current scheme either.
