There would also be Bluetooth 4.0 on that list.
Seriously take that and compare it to 4.2 or 4.1 and tell me its not comparable in terms of changes. The new point updates often times bring updates to apps and services. Whether you use them or not not withstanding. Google Now was huge in 4.1, but not everyone uses it.
I'm just saying, over the last few months we have seen a crapload of app updates, redesigns, development software rehauls, new software, new services and expansion of apps to other ecosystems as well as core android improvements. Those are the EXACT ingredients of a point update.
About the only thing else that I can think of that comes in point updates is bug fixes.
Edit:
Yea this is about the only thing I could say would be missing, big bug fix lists. But outside of that, over the last few months I think they have done the equivalent of a point update and some. Yet its still 4.2. They did say they were going to move in that direction, but its impressive.
