Per bug 769207 we want to remove support for mutation events and that the reason they haven't been removed already is that there is existing Web content using them. If we allow apps that use mutation events into the Marketplace, there will be a higher barrier to removing support for mutation events, since presumably we wouldn't want to break Marketplace apps. To address this problem and to make sure that we actually might have a chance of removing support for mutation events in the future, I suggest making mutation events unavailable to applications installed via the Marketplace.
