I don't get why apple does not take a similiar path on mac. Some websites are really apps for me (stuff like overleaf). I would gladly add them as apps and use this to unlock all those advanced functionality. But so far, at least on safari for mac, all those web-push websites are mostly spam. I only have a few where it is useful but I use them, again, like normal apps, and would be fine of adding them to my library. Nobody uses the mac app-store anyway, so why bother? Why not do it?
