Very interesting trade-offs!
I have made a claim about this proposal on The Ether, which allows for signalling of if you are for the more roll-up centric road-map or against the more roll-up centric roadmap.
Additionally, it will allow you to see the top arguments on the for and against side.
I did my best to summarize the core points of @vbuterin and @souptacular discussion so far, but feel free to write your own arguments that are better than mine in order to flesh out the trade-offs
