Of course it has few users -- it's brand new!

Is it out of the question to make new builds of those?

Anyway, ABI breakage will happen once in a while -- is it worse to do it 
now than any other time?

Do people that don't want (or can't) upgrade scipy/mpl/whatever HAVE to 
upgrade numpy?

For my part - I tried 1.4, found it broke a few things, so I downgraded. 
Then a bit later, we decided we needed to build a few things anyway, so 
have now gone to 1.4 and rebuilt scipy, and out own Cython extensions.

changing it back means that I'd have to do that again -- not a huge 
deal, but that's what I meant by "the cat's out of the bag"
