I agree "namespace package" is not a great name. I don't see any
particular problem with changing to a different name, though.

In my head I was thinking .pyns, but I thought people might pronounce
the "y" as a long "e". I hadn't thought of Godwin's law with .ns, but I
see your point.

Partial package works for me. I too like the association with partial
classes. ".pyp" is okay, although I'd avoid saying it stands for "Python
Package", since the presence of the file is not what makes this code a
package, it makes it a partial package.
