My AOSP launcher has zero permissions, except one that I optionally enabled to see notifications so it can do the little notification dots on my app icons.
Well sure, but that also means it’s rather limited in what it does. In theory if it had no permissions, it couldn’t even list the installed apps.
So I guess what you want to say is that it has some permissions, but none that leave the direct context of launching apps?
But even then… do you include a search box in that? Should that show recently opened files in apps, too? A rather common feature those contextual per-app run-actions, but they require some way of either the launcher getting this from the app, or in turn the app supplying this action to the launcher. Include a web search in that box? Sync settings? Show notifications? Gestures? All of these require a host of permissions.
I can see it requiring internet for integrating a search bar like it does, but why does their servers need that info instead of directly sending it to the search engine?
