With the previous implementation it was possible to dump the payload followed the schedule that produced it.

This is very nice! We do however need to have some mechanism to change the search space bounds from outside. E.g., sometimes you want to autotune with a larger search space. Maybe the bounds could be set in the constructor of the abstract schedule (i.e. one without concrete chosen param values)?
