We've been working really hard to keep the surface area of the product minimal so the dev team can stay nimble, which so far allowed us to ship features and stability improvements very quickly. We have a lot of really exciting updates planned for the next few releases, so we'd like to stick to the current model for now. After that, we'll start expanding the dev team and bringing some of the community drivers under the official RethinkDB umbrella. I don't have an ETA for this yet, but I expect this will happen within a year or so.
