That's interesting. I'm not sure if we can conclude of the absence of
full-rbf hash power at this moment, as it could also be a lack of full-rbf
propagation path towards such potential hash power. I think the day we see
an opt-out replacement transaction mined, it would constitute a good hint
of full-rbf hash power (assuming the tx-relay topology stays relatively
stable across the transaction issuance...)

Anyway, if/when the `fullrbf` patch lands in Bitcoin Core, including
automatic outbound connections to few `NODE_REPLACE_BY_FEE` peers, I'm
thinking of reaching out to a few mining node operators to advocate them
with the new policy setting.
