Missing signals in KWin::Output on version 6.6.1

Signals wakeUp, aboutToTurnOff seem to not be currently exposed, they were in version 6.5, here is a list of the fields that are available on output object using workspace.screens.forEach

geometry = KWin::Rect(0, 0, 5120, 1440)
devicePixelRatio = 1
name = DP-1
manufacturer = Samsung Electric Company
model = Odyssey G95C
serialNumber = HNTX101210
objectNameChanged = function() { [native code] }
geometryChanged = function() { [native code] }
scaleChanged = function() { [native code] }
aboutToChange = function() { [native code] }
changed = function() { [native code] }
blendingColorChanged = function() { [native code] }
transformChanged = function() { [native code] }
currentModeChanged = function() { [native code] }
mapToGlobal = function() { [native code] }
mapFromGlobal = function() { [native code] }

Is this intended change or should a bug report be created?

The dpms mode was reworked in 6.6. They were public-ish signals (edit: to be precise, they were intended only for effects). What was the usecase for those signals?

I did use them to emit dbus signal and then used that to toggle my lights behind monitor. Is there an alternative i could use now?
