There's been some ongoing behind-the-scenes discussion of the overall
NA problem, but I wouldn't try to give an estimate on the outcome. My
personal opinion is that given you already added the note to the docs
that masked arrays are in a kind of experimental prototype state for
this release, some small inconsistencies in their behaviour shouldn't
be a release blocker.

The release notes already have a whole list of stuff that's
unsupported in the presence of masks ("Fancy
indexing...UFunc.accumulate, UFunc.reduceat...where=...ndarray.argmax,
ndarray.argmin..."), I'm not sure why .real and .imag are blockers and
they aren't :-). Maybe just make a note of them on that list?

(Unless of course Chuck fixes them before the other blockers are
finished, as per his email that just arrived.)
