In draft spec here, request following changes:

• Move return_eligible to Item.return_terms
• Move replacement_eligible to Item.replacement_terms
• Add fulfillment_managed_by to Item.replacement_terms

Reason: Return & replacement of items is independent of cancellation. Cancellation of a fulfillment can result in return-to-origin (RTO) if the buyer refuses to accept it, irrespective of what return_eligible is. On the other hand, fashion items are generally returnable while some items (that are made-to-order e.g., cake) can't be returned, hence return_eligible will be false.

Goals: To identify the problem being addressed here and provide a solution.

Expected Outcome: Recommendation for changes in the protocol specification.
