WebIDL defines NewObject for APIs returning new objects. This allows doing some optimization at the JS binding layer. I would be good to have the same thing somehow for promises, although there is no WebIDL flags to help on that.

One option is to add to DOMPromise something like resolveWithNewValue which would take a Ref<T>&&/RefPtr<T>&&. Another option would be to use toJSNewlyCreated when resolve() is passed a Ref<T>&&/RefPtr<T>&&, although this may be too error-prone.
