I can think of another one:
There are some Bitcoin puzzle hunters who are currently struggling at the 66bit puzzle.
That's a good point, I guess those puzzles will (eventually) have the faith as transactions from leaked private keys: most if not all funds will go to miners. It was predicted
here and already happened
here.
The only way I can see here would be to run a full node, explicitly deactivate full-rbf (not to be confused with opt-in rbf!) and put your transaction in there.
That doesn't matter, other nodes can do full RBF anyway. And miners would be dumb not to do it: higher fees mean more income for them.
