I see the point of this change but technically infantry UU are still really useful, if you are in a late game setting with tons of food most infantry UU will still remain more pop effective than Champions, however if you make supplies affect UU it will be another nail in the Goth’s coffin (you can see this thread Request: Make Goths Okay Again) Basically the likes of Samurai, Jaguars, Throwing axemen, and so on are already good ways some strong civs can use to resist the only gothic strategy, so if those dudes get supplies as well it would be overkill
