Ok fair enough, but it looks like it's used for both reasons these days. 
Changing it would enable features in compat that don't necessarily have 
all the compat pieces implemented. I'd rather we work through the list 
of features one at a time. Geometry shaders is a little special in that 
we enable it only starting with the GL version where it becomes a 
required extension.
