HTTPS is being worked on. It turns out that just switching it on can easily break many forum features. One of my other sites rolled HTTPS out last week, and the Front Page of that site is still a jumbled mess as a result. And several commonly used forum features quit working, as well. Those bugs, on that site, are being worked on. If it weren't for problems like that, we'd have HTTPS on all our sites already.
I've also been notified that VS is rolling out a new signup page and process that will hopefully address those issues as well.
I know it's a scary world out there, but let's not jump overboard over a very, very slim chance of potential issues.
