Ok, if it is just a matter of adding symlinks, and apps can still link against libGL.so or libGL.so.1 or whatever, it seems fine. And I guess if nv is doing it, then it is probably not non-compliant. Anyways, I'm defn not the expert in such things, but I think there is some expectation that apps can link against a driver agnostic shared lib path an expect things to work with other drivers..
