Yes - as long as the wishes are backup-ed with a timeline and
volunteers for the implementation :)

Has there been any work on this ? I cannot comment on the feature
itself, I am not knowledgeable enough on that part of the code.

Same comment as for __array_prepare__.

My main motivation for an early numpy 1.4 is scipy 0.8.0. But if other
people think numpy 1.4.0 as it is now is too 'weak', making scipy
0.8.0 compatible with numpy 1.3.0 is technically possible. Then we can
talk about adding those features for numpy 1.4.0, and release it
