gstreamer1.0-plugins-bad
GStreamer Bad Plug-ins is a set of plug-ins that aren't up to par
compared to the rest. They might be close to being good quality, but
they're missing something - be it a good code review, some
documentation, a set of tests, a real live maintainer, or some actual
wide use.
This increases the attack surface of the entire system, for
functionality which is probably not even being used.

Note that the description for pidgin does not even mention video or
audio chat capability. If nothing else, it would be reasonable to have
one package for text-only pidgin built without farstream/gstreamer and a
separate package (with more discussion of the implications) that enables
that functionality and pulls in the dependency tail--so users can make
an informed decision about what they want to do.
