Not as an excuse for bad behavior but rather to consider infrastructure and expectations:
The packages might be cached locally.
There might be many servers – a CDN and/or mirrors.
Each server might have connection limits.
(The machine downloading the packages miiiiiight be able to serve as a mirror for others.)
If these are true, then it’s altruistically self-interested for everyone that the downloader gets all the packages as quickly as possible to be able to get stuff done.
I don’t know if they are true. I’d hope that local caching, CDNs and mirrors as well as reasonable connection limits were a self-evident and obviously minimal requirement for package distribution in something as arguably nation-sized as Python.
