Completely agree. What I'd do there would be make the change, then shoot off a quick message along the lines of: "Hey, I've made that change you suggested. A question though, I'm not sure I completely understand why you prefer it that way? Is it just a code style/consistency thing? Or is there something deeper I don't understand? If it's just style, do we have a style guide I should study? If not, would it be worth while me starting one as I learn these things along the way? Might help future new hires get up to speed quicker. I'd be happy to take that on if you think it's be useful?"
