I guess the app would have to handle not being allowed permission to do these things gracefully.

That's possibly a tall order based on my experience with apps these days, although for a difference reason: a lot of them assume there's internet connectivity, which isn't always the case, and a lot of apps don't handle this gracefully at all, even for doing things like opening maps, finding location, turning data off, going to another app, then back to maps again, and it takes ages for it to display because it's expecting to have network access.
