The concept is sound. You increase "velocity" by strategically decreasing your development effort, but this leaves out the idea of technical debt completely. I've start to believe there are things that will kill you in the short term (bugs), medium term (missing features), and long term (architectural issues). You can play with the percentage of effort put towards each area in every version/release, but neglecting any one for too long can kill the product. It seems easier to explain the balancing act to people that way.
