Your Environment
Using twine:
$ twine --version
twine version 4.0.2 (importlib-metadata: 6.0.0, keyring: 23.13.1, pkginfo: 1.9.6, requests:
2.28.1, requests-toolbelt: 0.10.1, urllib3: 1.26.13)
I have a setup.cfg with this classifier:
Development Status :: 4 - Beta
there is an extra space before the 4
If I build a wheel and run twine check, it passes (see attached wheel where the .zip extension has been added to make this tracker happy)
tracecode_toolkit_strace-0.21.0-py3-none-any.whl.zip
$ twine check dist/tracecode_toolkit_strace-0.21.0-py3-none-any.whl --strict
Checking dist/tracecode_toolkit_strace-0.21.0-py3-none-any.whl: PASSED
If I try to upload this to PyPI I get this error:
$ twine upload dist/tracecode_toolkit_strace-0.21.0-py3-none-any.whl

I would expect the check to fail if the upload would fail.
