Consider the other side of this argument: should reviews be timeless?
Many times a (good faith) vendor will make small, incremental changes to a product that addresses concerns that low-star reviewers point out. However, the product page remains the same - it does not distinguish between "Seattle Coffee Beans - Batch A" and "Seattle Coffee Beans - Batch C". It simply says "Seattle Coffee Beans".
So if you leave a review for Batch A, but the product being sold is now Batch C, should the review still be displayed?
