In another conversation it looked as though OpenBLAS was not robust
enough for a standard distribution.

present for 64 bit, correct? [1]

>From [2] it looks like Windows XP 64-bit is about 20 times less common
than 32 bit XP, meaning likely something less than 2 percent of
Windows users overall.  So - can we build windows 64 bit SSE2 wheels
for windows 7? With ATLAS for example? It sounds like they would be
fairly safe.
