> Actually, to take Python as an example, some functionality being in the stdlib have created a bunch of issue over the years since you can't just introduce breaking changes in an stdlib as easily. Look at urllib2/3 or xml in python. In the end, almost everyone ends up using requests and lxml instead.

And yet, I've been in situations where the only thing I had was urllib2, and I was very grateful it existed. It's awesome that the Python stdlib has everything it does, even if most of the time a pypi package is going to be superior.
