 Not for OS9 for this MDD, or so I've read on the web anywhere I've
looked; all the info I've found is that the only official release of
9.2.2 that's right for this machine is in the .dmg on one of the
set-of-4 install CDs that shipped with it.
 And even that image isn't an actual bootable installer, it's more like
a hard disk back-up image and the intent is to use Disk Utility in OSX
to "restore" the back-up to a partition and that's how you get OS9 onto
the G4 MDD 1.25Ghz. I was hoping that some bright spark might have
hacked a bootable version of it I could burn to CD, but I didn't find
such a thing when I was looking recently.

You may well be right about 9.2.2 specifically, since that is a minor update. The retail CD would likely have been 9.2 and then you're meant to use updaters.
I'm not sure about that particular model. It's possible that it wasn't designed to boot in MacOS 9, so the "installer" is only for installing the Classic environment to use under MacOS X to run older programs.
You could try one of these custom-made bootable installers (the second one is a newer version):
