This is really exciting - the team behind this really cares about developers and their experience. They see a way things could be better, and regardless of technical difficulty, say, "why not?" Forking a db? Brilliant. Offload expensive task to passive followers? Obvious (in hindsight). Instant, brain-dead db provisioning? Of course.

Personally, the only terrifying thing about this is that when Heroku releases something, it's been in the works for a good long while, and they usually have a stream of incredible releases waiting right behind it. The mind boggles at what they're going to be doing next.

But we'll be first in line for it :)
