It seems (unless I'm doing something fundamentally wrong) that iOS 16.2 (Possibly 16.0+) has introduced a massive regression to Screen Time when using Downtime.

Previously there was a well known hack where kids would change their date and time on device and extend scheduled downtime limits. Apple added a location services restriction which prevented this.

That now seems to be totally defunct. See screenshots below.

Am I missing something or is this a huge oversight?
