Review Comment:
I don't fully follow. If I wanted to take some C arrow data (let's say
coming from C++) and natively work with it - not using the "normal" C#
ArrowTypes, Schema, RecordBatches, etc. but instead manually calling into the
native functions on the CArrowArrayStream, that is no longer possible? Why not?
The reason for interoping at the native layer would be for performance - I
wouldn't need to allocate a bunch of managed objects just to interact with the
Arrow information coming from some other library.
