PEP 794 defines Metadata version 2.5, with two new multiple-use fields, Import-Name and Import-Namespace. The PEP was accepted last month. It looks like packaging doesn't know about the new fields yet. I realised this because twine uses packaging to check metadata, and so it's difficult to upload packages with the new metadata until packaging supports them (pypa/flit#779 ).
I'm hope to have some time to contribute this feature, but I can't do it straight away, so I thought I'd open an issue to record it, as there doesn't already seem to be one.
