Things come and go, and we have seen a number of deprecations in python already. urllib predates urllib2, while subprocess deprecates a number of things itself that really came from C. getopt was a port of the eponymous C library, which optparse meant to replace, which was itself deprecated on favor of argparse.
I would really not be surprised to see envoy, requests and so on come up in the standard lib at some point.
