Again good points, again thank you.
Places are intended to descibe set of components on page but not their
No. Activities are a set of "components" on the page. A Place, by definition, describes the "location" within the app, which you can interpret as being the "state" of the app, thus the "state" of the activities (it's rather the other way around though: you navigate to some place, and activities will construct their state from the current place)
