The default setting stays > **false**, i.e keeping opt-in RBF as a default replacement policy. I've > started to run the patch on a public node at 146.190.224.15. 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.
