There are a few other cases to consider. One is with packages that are
tweaked without forking the packages. For example if you were to
upgrade gstreamer you'd lose our pulseaudio tweak that makes sound

use totem for video playback (totem uses hw accel and works well, ff
internal one doesn't use accel and performs badly).
