This is very cool. An important area of ignorance (for me) is how well browsers do with local data. A nightmare scenario is that a user happily uses your app, stores data locally, and then Chrome decides they don't need localstorage anymore. What's the status on local data reliability in browsers?
Wise-men know better than to integrate google stuff into mission critical systems. Their behavior is purely governed by the information consolidation facet of any product or service they offer. Thus, given they already sample user traffic on 80% of the web, the company will continue to cull unpopular projects at astonishingly high rates.
I've lost count of the number of projects I saw get burned by this common mistake.
