Assuming the rules were consistently enforced: Users find apps for their iPhone on the App Store. There are no other app stores for the iPhone. Users do not visit an app's web page before they install it. Users will not find anything when they search the app store for e.g. "navigation app with pebble support". Users will not see Pebble support listed as a feature when they compare two apps. Developers know from the above that they won't gain any appreciable number of users by adding Pebble support. In that light I don't see much difference between banning mentioning a feature and banning the feature itself.
