Ahh, cool! Once this works I can copy it for NumPy :) Did you need to do anything special with secrets?

I just copied the same that we have been using for the multibuild-based version. The only thing that I think needs to be done is to redirect them to the GITHUB_ENV , e.g., so that they can be used later.

echo "TOKEN=$MULTIBUILD_WHEELS_STAGING_ACCESS" >> $GITHUB_ENV

The merged CI is failing with "ls: cannot access './wheelhouse/*.whl': No such file or directory"

I had a small typo above where I used ../wheelhouse instead of just wheelhouse. That code couldn't run until merged so hard to spot.

Nice. I wonder why some of the wheeels (it seems the manylinux_2_17_x86_64.manylinux2014_x86_64 ones?) doubled in size

Looks like cibuildwheel doesn't strip debug strings. Running strip -g on single .so file reduced it from 1.3MiB to around 250kiB.

Might need to manually specify something like
