When Ruby gemified the standard library, it wasn't about moving popular third-party libs
into the standard library as gems, but making large parts of the standard library separately updateable (and, in some cases, removeable); all of the standard library used to be the equivalent of "default libraries", the change was moving them from that status to default or bundled gems.
So, doing the same thing with Python would be less like bundling requests with python and more like moving http into a wheel that was installed with python but could be upgraded separately.
