FWIW, I agree it would be useful to add text to discuss the relationship
to NVO3.

It will definitely get review there, but to some extent it already is -
there are TSV and INT area feedback in this thread.

I agree that these issues should be addressed here too, though - to be
fair - some of them already are.
