I don't think it's the right way to do things. Turning off Bluetooth
completely will have close to zero effect on your battery consumption as
long as your device isn't discoverable. Should be the same for the
wireless.

Given those casepoints, the new "Network" dialogue will offer you a
flight mode, disabling all networking. For the other profiles mentioned,
the applications can already poke at gnome-session to disable "power
saving actions" within their remit.
