This new node policy setting enables to accept replaced-by-fee transaction without inspection of the replaceability signaling as described in BIP125 "explicit signaling". If turns on, the node mempool accepts transaction replacement as described in `policy/mempool-replacements.md`. The default setting value is `false`, implying opt-in RBF is enforced.
