Status change instead of deletion?

What do you think about an option to change status on expired carts rather than delete them?

For one of GSATi's clients, a common workflow was that customers would build their orders over time, often moving them back and forth through checkout stages and modifying the order a few times before eventually completing the purchase. These tended to be larger orders, which we want to encourage.

However, an order in Checkout: Review already has many things assigned to it that could become stale. For example, this client changes shipping methods/costs fairly frequently, and an older order sitting in Checkout: Review may have a shipping line item stored on it that is no longer correct. Deleting older carts would solve the stale data issue, but would not have been received well by our client and their customers.

Our solution was to create a small module that pushes older orders back to Cart, so that the user can continue building their order but must reselect the checkout details: https://www.drupal.org/sandbox/bpirkle/2577473

This conceptually overlaps with Commerce Cart Expiration in some ways. Would you have any interest in adding a status change vs. order deletion option to Commerce Cart Expiration? If so, I'd be happy to work up a patch for you to review.
