No standard library contains everything most people need, and sometimes the stdlib version is not the preferred. Look for instance at Python. Lot of people use requests instead of urllib for HTTP client. No-one uses the HTTP server. Until 3.x no support for async IO or event loops, so we have Twisted/gevent/eventlet, mostly incompatible.
