My first, and primary, programming language was C# which includes probably too large a standard library. It was definitely a surprise to see how minimal/simple other standard libraries are!
But they're there. I would much rather have a stdlib option which isn't as good as the most popular third party solution, than not have an stdlib option at all. You can't always count on being able to install stuff from pypi, but you can always count on the stdlib being present.
Broadly speaking, maintaining a big std lib is a huge amount of work, so it makes sense that a language team is conservative about adding new surface to a stb lib which they will then have to maintain for a long time.
What would that entail, just a package whitelist? A few renamed packages? In the python 3 transition they renamed urllib2 to just urllib, but now it's almost a dead battery too and you want to use requests.
