I think that this is a bad policy because:
1. An array is not always data. I realize that there is a big push for
data-related computing lately, but I still believe that the notion
missing data makes no sens for the majority of numpy arrays
2. Not every algorithm can be made to work with missing data. I would
even say that most of the advanced algorithm do not work with missing
Don't try to force upon people a problem that they do not have :).
PS: This message does not claim to take any position in the debate on
which solution for missing data is the best, because I don't think that I
have a good technical vision to back any position.
