Please describe the problem you are attempting to solve with this request

Currently twine allows for sdists in tar.bz2 format. However, these are rejected by PyPI. Should support for this archive compression format be kept alongside tar.gz? Is it allowed by other package indexes?

How do you think we should solve this?

I think this is similar to egg/wininst: PyPI and TestPyPI definitely don't support these, and I suspect that no other third-party indices do either given PEP 527.

Given that, I think this could be removed, but I'm curious what others think.

From some quick searching online:

• AWS CodeArtifact seems to support wheels and .tgz for sdists: https://docs.aws.amazon.com/codeartifact/latest/ug/codeartifact-concepts.html
• Artifactory mentions .tar.bz2 but in their own API/manual upload flow: https://jfrog.com/help/r/jfrog-artifactory-documentation/publish-pypi-packages-manually-using-the-web-ui-or-rest

I don't know how much the AWS CodeArtifact documentation can be trusted: it contains a twine upload command that does not work because the .tgz filename extension is not supported https://docs.aws.amazon.com/codeartifact/latest/ug/python-configure-twine.html
