Yea, I’m aware of the XY problem. It is still irritating when someone presumes to know your problem statement better than you and insists on having you change your question. Sometimes I simply want to learn the answer to this very specific question and not keep restating my problem until I find one the answerer knows the answer to.

A better way to respond would be: “Here is how to do precisely what you’re asking, but there may be a better way if you more clearly stated your end goal.”
