Yeah, maybe no 'official click this box' type way but as we've found the settings are possible and pretty easy to invoke.
Just delete these two files.
/Library/Preferences/SystemConfiguration/com.apple.PowerManagement.plist
/Library/Preferences/SystemConfiguration/com.apple.AutoWake.plist
If I delete those files, will the separate Display/System sleep timers come back? Or will it just do what this button does?

pmset sleep 0
Ummmm ... that doesn't revert to the old style. It just prevents the computer from sleeping. I tried it on my MBA 13
There currently is NO option to have the display blank out while the computer is still working - in order to save energy. You can't even do that with a screen saver anymore because there is no blank screen saver .
edit "/S/L/E/IOPlatformPluginFamily.kext/Contents/PlugIns/X86PlatformPlugin.kext/Contents/Resources/Your-Mac-Model.plist"
find:

replace:

<false/>
rebuild kext cache and reboot.

How do you find Your-Mac-Model? I know I have a MacBookAir6,2, but how do you translate that into the long hex string that's part of these .plist filenames?
