Steven, from the very beginning of Beta Features we acknowledged their would be Beta Features that were only for experimenting and exploring, that they wouldn't graduate. So this isn't a concern of mine. I think the only way we'll be able to get a good solid review of the controls, both internally and from users is to package it up as a beta feature and let people use the real production site with all the new controls in place. Matt's test instance is great but won't serve the same purpose.
