I had a similar thought a few weeks ago, but for smartphone camera and mapping apps (and the intersection of the two when it comes to world-based AR). Rather than every new app out there having to implement their own camera and map view, have them provide an extension that can be called by the native camera/map apps (providing the view bounds/coordinates/etc), that returns a rendered layer that gets overlaid on the view. Examples: In my state we have a govt funded web/native app that provides the fuel prices at all the service stations around you. If there was a mapping extension you could turn on, it would show this directly within the mapping app, and also an indicator "cheapest fuel within X km is at Y location" when you're in navigation mode. In camera view with an extension turned on, provide object detection similar to how QR codes are recognised.
