The "experimental" option does not solve the problem which is that the ndarray object now has masked fields which changes the fundamental nature of an ndarray for a lot of downstream users that really have no idea what has just happened.    I don't see how this has been addressed by any proposal except for the one I have suggested which allows a masked array object and a regular ndarray to co-exist for a time.    I doubt that the proposal actually helps get 1.7 out any faster either as there are multiple experimental APIs that would have to be created to pull it off on both the C and Python level.
