Possible to create wheels for things like pyjq and sign them for distribution?

From https://github.com/simonw/datasette-app/discussions/67#discussioncomment-1300040 - installing the datasette-jq plugin is difficult because it depends on pyjq which needs to compile an extension.

@psychemedia suggests:

Or at a push maintain your own wheelhouse and add a path to also look to that to install packages?

Would this require signing things for distribution for macOS? The wheel generated by pip install pyjq includes a _pyjq.cpython-39-darwin.so file.
