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.
