Why do you have to do this here and in all the UI surfaces?

[xdai1, 2016/06/16 17:00:13]

From my understanding, this work is mostly for experiment. Depending on the
dogfooders'/users' feedback, this work might be totally reverted in the future
or we might want to badge other Chrome apps from different categories (e.g.,
platform apps, webstore apps, etc) or badge Android apps instead. It might be
easier to implement it from UI level.
