Of course, they know that I have no doubt about that. What they will do is convert it to PWA so that it can be used more efficiently. What I am waiting are those apps known to be consuming too much memory from our mobile devices like facebook. I will be the first one who will download a Facebook Mobile Apps which is a Progressive Web Apps (PWA) already.
Many news sites and online shopping sites are PWA, also google maps!
Sorry but I think we have to clarify things about Google Maps. First of all, Google Maps is normally used online. But it has a feature which can be used as offline. How is it possible? By downloading the offline map (or it normally downloaded as cache) then using the Global Positioning System (GPS) and not the Local Area Network (LAN). Google Maps also launch a new application called MAPS GO which is just a Progressive Web App (PWA).
