Why?
She is pretty good with tech and understands how computers and phones work, but she just does not want to browse a process list to see which process is using the camera.
How do you know until you've tried?
At the risk of provoking a tangential discussion, I don't think keeping users "in the dark" about what's happening is ever a good idea. They don't have to learn if they really don't want to, but deliberate opaqueness is bad --- if anything, it only leads to more learned helplessness and ignorance. Of course, that's probably what companies want in general, since it means they can control users more easily...
Instead we have to explain to people that their photos aren't "in" the photos app and their music isn't "in" iTunes. It's the thing you mentioned: file managers will just confuse people so let's not include one. Easier to have them think of files as "living" in the apps we assign to open them.
Users do understand the concept of apps, obviously. A log of "App X used the camera", "App Y accessed your location" is well within what non-tech-savvy smartphone users can understand.
It's the same as you have an engine temperature gauge in most cars. I'm not really interested on what's going on inside the engine, I just want to know if the engine overheats so I can check basic things (cooling system leaks, etc) and if I cannot see what's wrong I wait and try to get to the nearest garage or call roadside assistance.
As a power user, I see value in a process list but I see why it does not take priority over other features.
Edit: spelling
So I think it's a valid thing.
Though iOS is getting out of hand with complexity these days.
Sometimes I want a dumb phone.
That's because iPhones were always full-featured general-purpose computers, just severely locked-down and restricted from user control. We are simply seeing the results of that opaqueness.
Apple already has this. Little orange dot indicates audio. There's a blue arrow for location access. I don't know if there's something for video or not.
You can then go into the Settings app and see which apps were using those features.
So that's a step in the right direction.
