Would migrating to the modern Safari extension API, which permits JavaScript injection into pages, be a better path forward here for this website modification tool?

Safari on macOS supports executing custom JS on web pages since forever, regardless of what version of API is used.

It’s not supported on iOS, though.

More accurately, it is not supported automatically. You can do Safari App Actions, but who wants to hit a menu on every navigation?

Ah. Thanks!
