So in other words the *ist and *ist-D use screw mounts with a higher level of compatibility than K/M mounts because the camera can't stop you. Isn't that just grand.

Yes. It is because the aperture lever in the camera opens up K-mount lenses. The aperture lever is controlled by a motor and making K-mount lenses work it needs Frankenstein type of engineering making the camera recognising that it was not an A, F, FA or FA-J lens, not a screw mount lens either, and then start the aperture lever motor while metering . It would be expensive and battery hungry solution only to please less than 1000 people world-wide.
The unfortunate fact is that too many Pentax buyers are too cheap and don't want to pay for costly features that will only please the few. You can always hope for a higher end digital body that uses two separate metering systems; one for K and M lenses and one for the rest.
