I think that something that the numpy community must be very careful
about is ABI breakage. At the scale of a large and heavy institution, it
is very costly. In my mind, this is the argument that should guide the
discussion: does going one way of the other (removing NA or not) will
lead us likely into ABI breakage ?

My 2 cents,
