The folks involved in the project have been pretty open about their project plans/timelines, speaking about it in webinars and various conferences, and have largely followed what they claimed. Making it available to the public undoubtedly could've been faster, but sometimes "move fast, break things" isn't ideal... (particularly for infrastructure that folks want to depend upon).
That's what it looks like to me as well. I klocked through the home page on mobile, feels like 25 pages of "why this is a good thing" and a bit of self congratulatory acknowledgement but I didn't get any hint on how to participate, use it or where to see the code.
