Yes, I think this is a good idea worth looking at. A few examples:
Disable passcode when I'm at home.
Turn on Bluetooth when I get to work.
Disable camera when I'm at work.
1. Security liability.
2. ok
3. What does that solve? You have the passwords, you could just go turn it back on. Might as well just choose to not use it in the first place if that's what you want.
I'd like to see the option to disable cellular data when I'm home or perhaps when in range of my home wifi.
Disable passcode when I'm at home.
3. Security purposes for those working in high security or locked down environments.
1. Yes, it is a security liability. But I'd say you're least likely to get your iPhone stolen at home. Plus, if thief A steals your phone, it'll need a pass code when he leaves the house, rendering the phone unusable.
Disable passcode when I'm at home.
Great idea, but it would require location services to be constantly on.
I think that would kill battery life.
