Russell, it is sad that this new Pentax user has a lens not up to spec, but your post is disingenuous implying that the seller knew it was failing. Before quoting this one post read the entire thread it came from and both sides of the story.
Back to the failing SDM. The approach taken at DPR was to try to engage JohnCPentax, regardless of his background he is a marketing person, I highly doubt his involvement influences anyone at Hoya/Pentax other than other marketing types. Besides nearly all those discussions have degraded into name-calling so I don't blame him for ignoring every one of those threads.
The easiest solution would still be a custom setting or per lens setting to enable screwdrive auto focus on those lenses.
