As pointed out elsewhere, we think of the minRelayTxFee as a minimum cost for the network to forward a transaction. When the minRelayTxFee was reduced recently, also the incrementalRelayTxFee was reduced, as it doesn’t make much difference whether you are sending a new transaction or use bandwidth to replace an existing transaction with an updated version of it. In the upcoming Bitcoin Core 30.0 release, they will both be 0.1 s/vB which means that you will need to pay at least 20 sats for the 200 vB transaction from your example for it to be relayed, and if you were to bump it, a replacement of the same size would need to increase the fee by at least 20 sats to be forwarded by nodes.
