just as a followup in case anyone is still wondering.. SCSensitivityAnalyzer does seem to be working as intended now on mac (incl in widgets & the widget simulator), and on device on iOS..
however it doesn't work in the iOS simulator, which may be expected? tho i can't see anything about it in the docs
at any rate, the simulator errors i get look like:
Error fetching CommSafety configuration from ScreenTime: Error Domain=NSCocoaErrorDomain Code=4097 "connection to service named com.apple.ScreenTimeAgent.communication" UserInfo={NSDebugDescription=connection to service named com.apple.ScreenTimeAgent.communication}
and
