The idea of a pledge is appealing because it's cheap right we don't have to monitor it's self-monitoring. I've not done this with my wife but a re you know a remarriage what I forget what they call her with a recommitment recommitment ceremony. People do these things as a way to publicly bind themselves but not in a legal or regulatory way but in a way of saying so and I guess the risk reminds a little bit of the way businesses will use a mission statement like "We are here to serve our community"
