Would it help to add a new class on the C++ side that is used only for
passing array data back and forth between C++ and Python? We have had
this before (SimpleArray) and it would be fairly easy to extend the
C++ with extra functions in the interface that use SimpleArray instead
of std::vector.

Then perhaps we can have one single typemap that hits SimpleArray
everywhere and converts it to a NumPy array.

And the work would be to add the extra stuff on the C++ side. The
advantage would be less complex wrapper code and that Garth and I
are capable of handling the complexities on the C++ side.

But what I don't understand is why it would be easier to write a
typemap for SimpleArray than for std::vector. Both of them use
contiguous memory.
