Making the release experimental as part of the next 3.7 update was approved by Ned (over email), so I merged the build. As soon as we snap for the RC I'll kick off an update and make the store page public, and hopefully can promote it enough to get eyes on it.

Unfortunately, I discovered as part of a test submission that the minimum Windows version matters, and it's a version that hasn't been rolled out fully yet because of some bugs, so there may not be that many people who can use it this first time. But that will improve over time, and I'm sure I can find enough people to flush out issues before the next release (anyone on the Windows Insiders program should be fine).
