+Another problem that namespacing would solve is the issue of choosing new names
+for packages following the agreed patterns of naming. Often (this is the case
+for Apache Airflow for example), there are public discussions that precede
+the decision to create a new package. The decision is based on the agreed
+name and follow the pattern of the existing packages. If more package names are
+considered during the discussion, all the names have to be reserved via a PyPI
+interface before the discussion is public, otherwise the names can be taken by
+other users. This has happened in the past as explained
+in the associated `discussion <https://discuss.python.org/t/pep-752-implicit-namespaces-for-package-repositories/63192/80>`__.
