PlayFetchIndex on a With*Animation trait conflicts with the animation concept, as it's bound to conflict with pretty much all 'normal' animation traits and blocks progress on the animation priority system. We also already have multiple precedent SpriteBody traits of similar kind, like WithGateSpriteBody and WithWallSpriteBody.
