[RndTbl] Raspberry Pi OS 12 bookworm and Wayland - no screen saver?

So, with all the hype around the new Raspberry Pi 5 (still waiting for 
availability), and the new OS version, I thought I'd give the OS a try 
on my Pi 400, and see how things look with the new Wayland-based GUI.

One strange thing I noticed (other than the slight increase in CPU use 
and slightly higher CPU temperature) is that there's no screen 
saver/blanker enabled by default.  Stranger still is there doesn't seem 
to be any way to enable it, at least not that I've been able to find.

The old X11/Xorg-based screen savers definitely don't work with Wayland, 
and I don't want to turn off my monitor (and have to remember to do so) 
every time I'm done using the Pi.  So, does anyone know how I can enable 
screen blanking in Wayland?  (Preferably with Pi OS and/or Debian 12 
bookworm, but any Wayland-related info would be appreciated.)

If that doesn't work, I may find myself reverting back to Xorg.
