It is absent from the Fedora Package. You should file a bug to
bugzilla.redhat.com as there is no reason to exclude this element. What
I think is happening, is that what you see is from the registry cache
populate using you system installation. What you can try is to remove
that registry cache:

  rm $HOME/.cache/gstreamer-1.0/registry.x86_64.bin

If you have multiple installation of GStreamer, it's often preferred to
use different registry cache. You can choose you cache file setting
GST_REGISTRY environment.
