Additionally some miners mine full replace-by-fee, which has no limitations on
nSequence. My implementation (for v0.13.2) is here:
and is identical to Bitcoin Core modulo the nSequence stuff being removed, and
a special service bit added to allow full-rbf nodes to preferentially peer with
each other to make sure replacement transactions get propagated.
In practice full-RBF works fairly well, so while it's even faster to use the
nSequence signalling specified in BIP-125, doing so is not mandatory so long as
you can et your replacement transaction to a full-RBF node.
