Bitcoin Core contributor rkrux argues that keeping the outdated flag is now hurting user privacy.
Can Wallet Standardization Enhance Privacy?
The original purpose of opt-in RBF was to allow users to replace unconfirmed transactions with higher fee alternatives. However, with full RBF now in place, this signaling mechanism is no longer necessary. In fact, its continued use can create unnecessary transaction data that can be used to fingerprint wallet behavior.
By removing redundant RBF signaling, wallet developers can help minimize the amount of identifiable data associated with transactions. This change could make it more difficult for outside observers to track user activity.
Standardizing wallet behavior is seen as a key step in enhancing user privacy. By reducing the variability in transaction data, wallets can become less distinguishable from one another. This, in turn, makes it harder for third parties to identify specific wallet software or track user transactions.
