What language does this apply to?

Python 3.8

Describe the problem you are trying to solve.

The wheels on PyPI doesn't have google/protobuf/pyext/_message.???.so file if I install the package with pip of Python 3.8. In this case pip use protobuf-X.Y.Z-py2.py3-none-any.whl. Thus python module google.protobuf.pyext.cpp_message is broken to import. In fact, I don't use the latter, but I need to import classes from google.protobuf.pyext._message (sorry).

Describe the solution you'd like

We need wheels with compiled libraries for Python 3.8.

Describe alternatives you've considered

Downgrade my project to 3.7.
