According to CoinDesk, Bitcoin developers are discussing the removal of the explicit Replace-by-Fee (RBF) signal from the Bitcoin Core wallet. Developer rkrux stated that since full-RBF has become the standard strategy, the BIP 125 RBF signal has become redundant and may leave unnecessary wallet chain fingerprints.
Community member Murch noted that stopping the sending of replaceability signals is not simply about removing "fingerprints," as each sender still has to choose a sequence number for each input; currently, about 75% of transactions have used specific sequence numbers, primarily MAX-2. rkrux indicated that the default input sequence number should adopt best practices recognized by a broader wallet community.
