Yes, that was always the intent. Think about it from the perspective of Object.defineProperty. If you are defining a new property a missing attribute is supposed to mean use its default value. If you are redefining an existing property a missing attribute is supposed to mean keep the existing value. Most of the logic in [[DefineOwnProperty]] is rejecting invalid or inconsistent redefinitions.
