Yes, packaging was removed from 3.3.
Details here - http://mail.python.org/pipermail/python-dev/2012-June/120430.html
This message claims that the packaging module would be merged back into the CPython repository after the 3.3 release, but that doesn't seem to have happened. Also, there doesn't seem to have been any work in http://hg.python.org/distutils2 since May. This leaves me confused about where the current distutils2 development is happening (or is the project dead?).
