Most of the time on healthy network we see new transactions appearing that are not present in the mempool. Once they get into mempool we don't ask for them again when some other peer sends an Inv with them. Then these transactions are usually added into block, removed from mempool and no one actually sends them again to us. Some stale nodes can do that, but it's not very likely to happen. At the receiving end at the same time it's quite expensive to do full chain HasTransaction() query, so if we can avoid doing that it's always good. Here it technically allows resending old transaction that will be re-requested and an attempt to add it to mempool will be made. But it'll inevitably fail because the same HasTransaction() check is done there too. One can try to maliciously flood the node with stale transactions but it doesn't differ from flooding it with any other invalid transactions, so there is no new attack vector added.
