Unfortunately it is an undefined function in the KAF and KAF2 mounts.
Since it is undefined, they could simply address it, in the same way they could address the K10D Metering issue for Manual apature lenses, the solutions are easy nad only software.
What really gets me is they go our of their way to advertize that the camera will function with every lens they ever made, and yet there are fundamental errors, where it does not function as it should. The teleconverter issue is one, the exposure for K10D and manual lenses is another.
They need to make the cameras work in a reasonable manner, otherwise they will loose credibility as a maker
