Yes, I've heard about concerns of stunting plants by cutting them or doing almost anything to them... I don't share those concerns though.
I agree that High Stress techniques like topping/fimming/supercropping are likely to drain the plant somewhat and that excessive pruning leaves wastes stored energy .... I can't see that getting rid of buds and stems that will be worthless at harvest can be negative to the plant, it can use energy that would otherwise have been wasted.
