As a tool its a good thing.
As a general website a PWA such a blog is a no but as a tool such as the ability to complete a form/document offline, add photos etc is very useful so for say medical or insurance purposes a like (i make PWA's and Hybid Apps for the App stores) these can be essential, but for getting the latest news basically its just a fancy bookmarker.
The main reason PWA are being pushed Google (and Apple in some respect) are pushing these is that they don't have to go through an App store for the user to install them so there is less work for Google Play to interns of management and platform support, essentially they can spend less.
If anyone want to try and make a PWA its rather easy then you just need basic javascript skills and a little HTMl knowlage. Install node.js and then Angular/CLI and a quick visit to youtube for a 5 min tutorial. Deploying your all you can use something like Google Firebase project as a server, no messing around.
