The idea of identifying and removing a bottleneck isn't new. I don't know about randomly removing "blockers", it's generally widely accepted that only the bottleneck makes sense improving, everything else is wasted work as you'll just accumulate work in progress. People sometimes rebel a lot against this because "my code is a creative process and that's for factory lines" but I've never found myself worse off when improving a bottleneck, though you do have to fight the "but everything counts" crowd.
