He may have one set of packages -- but he knows that not all
of them work together. Moreover the set changes over time -- because
new versions are released -- and finally the downloader is the one
who has control over what he really installs on its local machine.
Maybe, that's the equivalent to "I am the one with the final say".

Yes, we have less control over what is released on PyPI than a Linux
But, you have control over what components your project depends on -- and
you can select components based on underlying release care.
Okay, you can also fix the dependency and thus skip careless releases...

You must have far worse experiences than I have.
My components usually work across many releases with
only very rare need to intervene (Five twice broke one of my
products; I think that almost was it).
