Great questions, Annika.
The S15 Budget can be found here. The tl;dr is that S15 total request (no reserve) was $983,429 and S16 is now $1,100,689. A difference of $117k. S16 now also includes Saas costs that the foundation was absorbing ($90k for the season), the MC team and the loss of a couple of folks.
The short answer is yes that we will be slowing down the Moonshotty type experiments while we focus on our Essential Intents for a couple of seasons. We might still hire out some of this work via the foundation (ie, the governor contract upgrade, the Grants Protocol launch experience, etc.) but we have not made any final plans yet.
I wuold love to defer to @GTChase on this one 
Overall, we wanted to ensure we defined the outcomes we cared about without being overly prescriptive in how we accomplished them.
