So basically solve a problem with another problems (trusting a foundation) 
Automated checkpoint every n blocks (between 144 - 2016 should be good) is simpler and more effective (for 51%+ attack and history manipulation, not selfish mining).
Besides by trusting a foundation, there's no point of consensus method or even decentralized system. We might as well turn back to centralized system (e.g. bank).
