I mean, the problem is the same one introduced since the two big mobile platforms were established: "I want to publish to IOS/Android as a native app without needing to have two separate builds to manage". PWAs make that pitch to those who already have websites to triple dip. It never has to promise to be as good as a native app, just "good enough".
Does it live up to that? YMMV. It's probably fine for very simple apps, probably comes apart at the seams for anything trying to look modern or have fancier functionality.
