Mmm looking more closely I am not sure this is something we want/can do.
As the driver expands, it looks likely that some of these types will be
used outside of the `gsp` module - in particular some of the responses
can be used outside, I think this actually happens with the MM series.

So I think I will keep the visibility as-is for now.
