Storage is relatively cheap. Packages with only one release and little usage in the wild will be a rounding error in cost. A few years ago, Pypi required an over million dollars equivalent in CDN traffic per month. Storing a million of small dead packages is not worth the concern.

While my research was very shallow, the issue is with the practice. And I didn't look at how large those packages are.

It might not be a storage problem right now, but the practice of publishing crap is dangerous, because it can be easily abused. I think it is very easy to publish via pypi a lot of very heavy packages.
