BTW I changed one of my OTS calendars to issue fee-bumping txs without the
opt-in RBF flag set as an experiment. I also made sure txs would propagate =
to
the above node. As of right now, it's up to 32 replacements (once per block=
),
without any of them mined; the calendars use the strategy of starting at the
minimum possible fee, and bumping the fee up every time a new block arrives
without the tx getting mined. So that's evidence we don't have much full-rbf
hash power at this moment.
