Here's a quote from the link that iridiax provided. It's pretty much what we though was coming - Supplemental Index information will not available to webmasters anymore:

...Supplemental Results are fresher and more comprehensive than ever. We're also working towards showing more Supplemental Results by ensuring that every query is able to search the supplemental index, and expect to roll this out over the course of the summer.
