The extra deps in IPython are for backwards compatibility, so that if
people have scripted (or remembered) commands like "pip install
ipython[notebook]", they will continue to work, by pulling in the
separated package which now contains that functionality. In time we will
probably remove these.
I'd recommend that you ignore these compatibility dependencies (that is,
all the extra dependency groups of IPython besides doc and test).
