I wear one when I ride english, but then again, I show all around. I wear my dickie because it is convenient, and faster to get on and off than a button up shirt. When you show all around, you have to be able to change your outfits and tack within a short amount of time. No one can even tell that I wear one, and if jackets are excused, I still keep mine on. I'm not necessarily bothered by the heat in my jacket, so I don't mind.
