I had a offline conversation with Daniel about this since there are other triggers - thermal constraints and game-like apps being examples

"performance" mode to mean the existing code paths and "power" mode to mean *additional* new heuristics for energy-efficiency. The power supply assumption is just the first one of those heuristics.
Well, so now the question is whether or not we relly want to always go to the "power" (or "energy efficiency" if you will) mode if the system is on battery. That arguably may not be a good thing even for energy efficiency depending on how exactly the modes are defined.
Nobody is talking about always. But in general it seems a good enough approach. Hell, many of the AC/BAT switches in todays power management crap things are not always right.
Do I want it to dim the LCD further when I unplug the laptop -- mostly no, but still it does. And the most annoying one is that it reduces the screen blank time to something near 5 seconds or so.
Why would this be any different? If you know what you want you can turn the knob.
So in my opinion it's too early to add things like that at this point.
Meh..
