Currently Sympl (as of 0.4.0) does not include tracers in input properties. This was done in part for internal reasons, but I'm not convinced this is optimal. If I can find a way around those internal reasons, I think it's better to be explicit and list tracers in the input properties (automatically), the same way they're listed in output properties. Making this issue so I remember to take care of this.
