I think this makes sense for cases where there is easily reachable consensus. What happens when we can't easily reach consensus? For example it doesn't seem like we have consensus on funding improvements to swscale (compared to integrating a 3rd party library). Does that mean that work cannot get funded through SPI? 

This is where I think using the TC to make a decision where the community at large cannot reach consensus might be useful. It doesn't need to decide the fine technical points of how the work is done, but it can provide a useful mechanism to disagree and commit about whether the work should be done at all and provide the broad strokes (like improve swscale vs write a brand new library vs integrate some third party one).
