Most dividers I have seen utilize antikickback pawls and they actually work pretty good........ if they are installed.

After some looking around I think the Riving Knife is the new version of this old stand guard and does allow for some slightly better safety as some knives do appear to be able to stay on for those non through cuts as Adrian mentioned.
