I'd have to think about how it would work to deal w/ variants that
have params not wrapped in a struct. It at least sounds annoying, and
I tended to think the benefits of using a struct where enough of a
justification to change this. (Plus there are not many usages of this
API yet, so seemed like the perfect time to cleanup.)

*maybe*, but I can't think of anything.. right now it is only the
sampler_view and stream_output_target state that I handle "manually"..
but those are also kind of different from the rest since they are
already refcnt'd. And I figured it was easier to just deal w/ those
manually than implement a 3rd type of state (CSO vs Param) in
rsq_state.py..
