That's a valid reason for keeping it. On the other hand, it gets very little
use, is pretty much undocumented and probably more buggy than most other
parts of NumPy. There is also not a really good use-case for it (otherwise
new users would ask about it). And as Stefan pointed out when asking this
same question last year, object arrays would do nicely if one needs this
functionality.

Would it make sense to put clearly in the docs that this module exists for
backwards compatibility reasons, and is not recommended for new development?
