The demand for this is very low, too low to justify the cost and effort. I realize some people would like to see this and other exam related things around VFP, but it simply turns out that not many VFP developers use this, unfortunately. The reply you received from Microsoft Courseware Support explains things pretty well and you should not expect any changes to occur relative to this issue.
