I think it's better as it is than as a feature in WikiFeatures - now individuals can turn it off rather than having a (possibly confusing) wiki-by-wiki difference over which you have no influence. If you compare it to the other things in Features and Labs, it doesn't really fit in there as the highlighting is more personal experience than wiki design.
