I have had a FOSS web app for learning arithmetic for quite a few years. I occasionally review it, and make changes. Each year Chrome and Safari both nip at the edges of what allows a PWA to be OK. No one really cares until one has to write documentation helping folks install the PWA and avoid issues that did not affect the PWA a few years ago. I mean really, are Tim and Sundar really that afraid ?? I guess so. They have dozens of millions on the line. Capitalism... gotta luv it.
Hmm, I'm making a site and I planned on using a PWA for the app experience instead of a native app. Am I setting up for a bad time? I'm not too worried about the installation hurdle, my potential early adopters are motivated and smart.
