If it helps, I can assure you personally that it will. Roots is being aggressively developed right now and is already in use for several high-visibility projects at the company I work at full time. If anything, in a couple years roots will have expanded quite a good amount and, based on my current plans for the future, it will ship with a compiler that several orders of magnitude faster, be quite a bit more flexible with more languages and templates, be coupled with an optional cheap and efficient static hosting service with post-deploy compile hooks, and have a well-developed dynamic CMS that it can be paired with.
