Have tested locally that this improves wheel selection.

Do you have an example of a package that requires or uses this? If so, I can push up a test case for it to this PR.

@j-baker Can you add a test case for this? I.e., build a package for which these changes are required?

Alternatively, if you can simply name a package you're working with that doesn't work without these changes I can add one for you.
