Actually, I like to think about the SPS as being able to separate direct funding from voting based funding. Imagine that you transitioned all of Utopian to fund its activities based on SPS. It's more stable and you have better control of how much goes out to whom with better accountability. So whatever % utopian is allocating from the rewards pool now can be shifted to this instead, and it doesn't have to be a loss relative to today. Of course with a fixed ratio going to SPS, it's not flexible enough to do things like "send remaining funds back into the reward pool" but that would be neat too, wouldn't it? (Can be one of the first things funded if it's desired)
