So? When your requirements change you change the local mirror.

Some reasons I've seen mentioned in the past:

* In some big companies it might be easier to publish archives on the company webserver than on PyPI due to truckloads of red tape on their part (not something we can fix)

* It is easier to publish all related archives in the same place for projects where the python package is just one component (for example client libraries for a network server)

* Authors might not know it is possible to upload archives to PyPI

It may be as simple as lack of knowledge (e.g. "I didn't know I could host files on PyPI"),
or unnecessary friction in the release proces. 

I guess the only way we will know why some authors don't upload archives to
PyPI is to ask (some of) them.
