Not sure why your comment was down voted, but I guess some people are just negative on PWAs in general. I believe their views will change as browsers improve (and Apple starts embracing the PWA, as they have started with service workers etc). Eventually we will move towards a standardised platform for software on the web, and it's quite likely this platform will emerge from current day web browsers.
I hope so, it's a transition period at the moment and there isnt yet a 'standard' way of doing things that just works.
The system at work is just a regular web app (that I'm in the process of modernizing), I also have a side project I want to build but I've no idea what I'm going to use, leaning towards Vue/vuex with net core as the backend with the eventual plan been to move more PWA as things settle out and improve.
I'm thinking of doing a PWA in the near future for work system so I'll keep an eye out for your stuff :).
