Also, I do not know how many people use this particular feature.
However I would point out that many people who use numpy are not also
on the mailing lists.  Most of the STScI do not follow the numpy
list.  I serve as our point of contact to the numpy community.  I'm
trying to gather a list of projects that use this feature and specific
use cases for you.

 As I do not use this module myself I cannot
counter your arguments at this time.   If we decide to deprecate this
module would we reverse this decision if we then find out that the
assumptions that went into the decision were in error?

Another concern is that we told people coming from numarray to use
this module.  It is my opinion that at this point in the numpy release
cycle that an API change needs a very strong justification.  Anecdotes
about the number of users, a "change or die" philosophy, and an un-
articulated notion of  "the spirit of numpy"  do not in my
consideration meet that high bar.

 If you would like us to provide
additional documentation and tests that would be possible.  I'll do it
myself if that is the only think keeping the module from remaining in
numpy.
