I think the example is too contrived. Like you said, make a non blocking comment about the name and be done. For less trivial examples, oftentimes I think honestly asking "why did you do it this way?" Before making a suggestion is a good idea. Often we dont have the same context nor know the intention. Emphasis on "honestly." If you just want them to do something differently then suggest that directly.
