That would make sense then. I've definitely been silently opted-in - there was no indication of it happening, I just got confused when I hit the "Newest caches" button (as I'm want to do).
It's not necessarily an issue for my workflow yet, but I thought I'd point it out here as I assume this is the place to list bugs with the new map.
I was aghast at first, but I'm getting used to it now.
