Wes McKinney commented on ARROW-2068:
-------------------------------------

I had been thinking that the returned buffers would correspond to the vector 
layout according to the format specification, so the first element would always 
be the null bitmap (which may be None). So this attribute or method would be 
intended for users who understand the buffer layout. [~cpcloud] [~xhochy] any 
thoughts on this?
