No, sorry for the confusion. The wiki is clear about sport=*: "Since this is a non-physical tag it should be combined with one of these (physical) tags" It has nothing to do with the renderer, though. In fact, the wiki specifically cautions you not to worry about the renderer: "Though most of these tags are rendered when used stand-alone, a combination with a physical tag is strongly encouraged to avoid misunderstandings."
