Even if it didn't provide support for a given platform somehow, at least the 'automated' build would be available publicly for modification and patches could be submitted (and maybe accepted).  That would be a great step forward in my opinion.  The lack of any reference builds has certainly been frustrating for me (or I'm just silly and missed it).

I don't know what you mean by reference builds.

As I said, there is no "wheel build script". There is an internal (private) build and CI infrastructure which (amongst other things) generates wheels. The aim is to replace the various configure.py scripts with setup.py equivalents so that the regular Python tools can create the wheels.

I'm trying to reduce the number of builds, not increase it.
