That's kind of a moot point - most Android devices are not Google's own phones, so you can't ship a reliable user experience on most Android devices.

My point was more that if Google can do it, other manufacturers can do it.

The issue with other manufacturers is that they concentrate a lot more on features that are visible to users whereas features like these aren't necessarily visible directly to the user and aren't given attention even though they're possible to implement.
