A field name that is not in the writable set is no longer dropped silently — the request is rejected with 400 INVALID_PARAMS and the error text lists the writable names. Read-only fields that appear in product-row responses (priceAccount, ownerId, storeId and others) are still accepted and ignored, so an object read via GET can be sent back as is.
