It's progressive because you're progressing the permissions and features the website can access beyond those of a normal page. It has nothing to do with progressing the web to 90s style app installation and the update mechanism is nothing like that either, it functions as a locally cached webpage not as something you need an SCCM push to load a new binary or something. PWAs do not have to be accessed through desktop icons either - just launch them through the browser's interface as you seem to prefer. If you've ever seen a machine with a default Chrome install then it had about a half dozen PWAs installed without any such desktop shortcuts.

The best uses I've gotten out of PWAs are on my Linux machine where there either isn't a native app or I wouldn't trust installing one from the manufacturer if there was. At the same time I don't want random websites to have access to the permissions these apps would need so I load the PWA version of the website and now I've got the ideal island of something served as a website but with the elevated permissions it needs.
