> the compatibility issues are pretty much a thing of the past on any browser
Because there is only one meaningful browser left: Chromium. It is not a solution to cross-platform, it is just pushing for a monopoly. Just like a few years ago you could have been advocating for supporting exclusively Internet Explorer: that solves the compatibility issues too.
Now PWAs are not trying to kill other browsers (it's done already), but other platforms. That's just the next step.
