Yes, but afaik they still expose the "hardware" OpenGL interfaces,
which is what we're talking about here.

ARB as in ARB_vertex_program or ARB_fragment_program, I'm not sure
what multitexturing has to do with it. You can't, for example,
properly use ARB_fragment_program together with a GLSL vertex shader.
(You might be able to get away with it due to the way GLSL is
implemented on a specific implementation, but you're certainly not
supposed to).

Except that there are no actual meaningful combinations to make.
