That's more an issue with the state table design than a reason to
create a new shader backend. A more hierarchical state table would
probably have helped there, but the general issue you're trying to
solve is that you want the state table to change depending on the
available extensions and wined3d configuration. I don't think that's
limited to shaders or fragment processing. If a GL3 spec ever actually
gets released, and actual drivers start implementing it, we'll run
into it there as well.
