I made the second PR for full wheel with openblas. It is reviewed, but rejected as solution with linaro built openblas is not good enough, so I am investigating alternate options for cross compiling openblas.
While I am working on this I have one question about the wheel without OpenBLAS. As the job is now created on the main it can be triggered manually and the produced wheel can be used for publishing to PyPi. I'm wondering what the next steps are with this build. Is it planned for the wheel to be built/published without OpenBLAS and what would be the conditions for that.

I don't think we would make an official release to PyPI without OpenBLAS functionality, and we would want any official wheel to be built on CI infrastructure that we can configure ourselves.

I guess it might be possible to upload an 'unofficial' wheel to https://anaconda.org/scientific-python-nightly-wheels/numpy that doesn't have OpenBLAS. However, we would want to be building that via one of our CI workflows.
