Catanzaro: GNOME Core Apps Update

* The browser argument can be nowadays applied to *anything*, it can be the runtime environment for whatever, given WASM etc.; see all the apps that use Electron, and not everybody is happy with that.

* Developers are volunteers and they decide themselves what kind of app they want to develop. Perhaps they want to maintain the possibility that Maps will have an offline version too eventually.

* GNOME exists in cellphone, tablet and embedded versions too, some with rather modest hardware capacity.
