One major one for anything with a text input it the inability to know when the keyboard is open and closed and how large it is.

It’s very common for something like a comment box to keep the text pinned above the virtual keyboard. This is impossible on the web. If you have ever seen an implementation of this on the web (for iOS) please point me in that direction as I would love to copy the implementation.

Notifications just came recently, but weren’t available for a decade after availability to native apps.

The final hurdle is discovery. It’s not possible for a site or app to act as a one click installer of a PWA (add to homescreen) and sites can’t prompt to be added.
