[$] Namespaces for the Python Package Index

The Python packaging picture is generally a bit murky; there are lots ofdifferent stakeholders, with disparate wishes and needs, which all adds upto a fairly large set of multi-faceted problems. Back in the first threemonths of the year, we looked at variousdiscussions around packaging, some of which are still ongoing.A packagingsummit was held at PyCon 2023 to bring some of the participants of those discussions together in one room. One of its sessionswas on addinga namespaces feature to the Python PackageIndex (PyPI). It provides a look into some of thedifficulties that can arise, especially when trying to accommodate a long legacy of existingpractices, which is often a millstone around the neck of those trying tomake packaging improvements.
