No, but it should be in the spec/documentation for the tool that builds sdists or wheels. That is, when metadata 2.0 support is added to distutils/setuptools/... it should document how the metadata is configured.

So a package author creates a package that only works with Python 3, builds a sdist using a tool-specific option that states this, and that data isn't recorded in the sdist so that whoever uses the sdist to build a wheel has to find that out elsewhere and re-specify it to build a wheel? That sounds wrong, unless I'm misunderstanding you...
