The minRelayTxFee and incrementalRelayTxFee both express a minimum cost for relaying data across the network. It would be a bit odd to charge more for the first announcement of a transaction, but then make it cheaper to replace the transaction, or vice versa to make it cheap to make a first announcement and expensive to replace a transaction. So both mempool policies were lowered from 1 s/vB to 0.1 s/vB in Bitcoin Core 29.1 and the upcoming v30.0.
