I hope you didn't believe that merits a response <0.5 wink>.

That's all true of every module that's not in the core distribution.  If the
NumPy maintainers really wanted it in the core, I bet they could prevail --
but I doubt the current crop of core Python maintainers has the bandwidth to
take this over from them (the PythonLabs crew does not), let alone to
reinvent it.  So "really want" includes volunteering ongoing work too.

Same here.
