Save planner objective after running discretionary_policy

For some reason discretionary_policy.m has the commented line

%oo_ = evaluate_planner_objective(oo_.dr,M_,oo_,options_);

Is there a reason we do not simply add

oo_.planner_objective_value = evaluate_planner_objective(M_,options_,oo_);

to the function to actually save the objective function value as for Ramey?
