Yes, micro-optimization with manual instruction scheduling is usually a great idea. No, macro-optimization with manual instruction scheduling is usually a bad idea. That it "doesn't remove" something isn't an argument that this is a good idea when the selling point is that it enables removal. The "novel" idea here is the macro-optimization, with some overtures about making the micro-optimization easier - as you likely know, this is not true since the complexity here is more about understanding how to do better, not about what language features you use to make those changes.
