It's possible that this will be released in a couple months (and with a slight chance it may be longer). Sorry I don't have better news for you.
Thanks Joel. I'll keep an eye out for it.

The Service Notifications app is an internal-only application; I don't believe that we have plans (currently) to build a publicly available version. You'll note that in 4.2.3, it is no longer listed (even as "Coming Soon"); its inclusion in 4.2.2 was unintentional.
