I use iOS on a work phone and an iPad. PWA is nice on the iPad for connecting to web admin pages of devices/sytems (even better on the iPhone for just checking stuff). It's already frustrating that I can't force it for any web page, it has to be coded on the web server.
Bummer. But also another reason the iPad is a convenience device, and not a "working" device. The size and screen are great, battery life fantastic. But a Lenovo Yoga would blow it away (at 4x the cost).
