Android's fundamental assumption is that suspend is the normal state

And mine too! I want my battery life to be maximum, so if I'm just reading LWN, I want my laptop to put everything to sleep except the screen! I am doing nothing else, and so should my laptop. Then I want aggressive standby, with a quick resume from it (forget hibernate for now), and a pony too, of course...

In Android, if the screen is awake, the power management process is holding a wakelock, so everything is running, nothing is suspended. when the system suspends it turns off the screen.

That's not fundamental to the design of Android though. If some hardware is capable of keeping the screen on during suspend (as current phones are capable of keeping the audio device on, for example), or if it has an eBook style display which can continue displaying without powering the screen, then the policy could be changed as appropriate.

This sort of scenario came up a few times in the recent suspend blocker discussion on LKML.
