Yes.  We don't want to end up like we did with policies where there is
no plan or schedule for removal.  We are carrying along quite a bit of
code (and complexity) only to support policy OLD behavior.

Yes.  The protocol should have its own versioning.  IIRC the earlier
discussion that proposed using the CMake version was back when we
were going to put all this in a .json file on disk during generation.
For an interactive protocol session it makes much more sense to have
a dedicated protocol versioning scheme.
