Nitpick: that's actually not necessarily true right now. There's enough people running really well connected full-rbf nodes that a node that accepts incoming connections has a reasonable chance of being connected to a full-rbf node.

But certainly, if you want your full-rbf txs to be guaranteed to propagate, run this: https://github.com/petertodd/bitcoin/tree/full-rbf-v25.1

I'll have a version for v26 soon too.
