Sure, but without something more concrete to support criticisms, it's only a theory, however compelling the reasoning, that this might be a bad approach. Right now it reads like a detailed literature review. Such things are usually the starting point for research, not and end in themselves. I think the authors make a promising start here, but I look forward to further work from them so that if their criticisms are correct the field can turn to more fruitful approaches.
