I agree with the use of commitment forms, just like our academic integrity statements and various conformes that we have to submit as government employees. Most of them are really "non-binding" and penalties are not really enforced, but I believe that having a reminder in writing serves as a deterrent against being delinquent in fulfilling tasks. I think they also reinforce good behavior especially when they are newly signed, which is why it is good to have the commitment renewed regularly.
