Does this mean that passengers from these stations can no longer get
railcard discounts on (off peak) travel cards and other journeys
within the zones? If so, they will notice a significant fare
increase.

No, I don't think so. Why should it mean that? Are you suggesting that
railcard discounts are not available within the zones?
