Agree. I also prioritize why then usually how with what dead last. I focus on why because it helps simplify and clarify requirements. However the who is our current customer set, which we knew already. Customer's will balk at a great why if it doesn't align with their sense of value for the money they pay. So in fact after the first cut of why there will be refinement as business people check through as customer proxies and how much effort it takes. So why in the absolute sense is neither independent nor so superlative that it stands on its own. Why helps with strategy and the long game (right requirements now means less labor redo later) but we will always have a primary dependence on who -- customers who assess what we do.
