I like the idea of pure replacement by fee rate, but I'm not sure
about the 2x coefficient. I'm afraid it can result in overpaying.

What is the purpose of the 2x coefficient? Is it needed to prevent DoS
by continuously increasing feerate by a fraction of a percent? Isn't
1.1x enough to prevent this DoS vector? A rise from 100 sats/byte to
110 sats/byte is easier to bear, then a rise from 100 to 200,
especially if the next block feerate is 105.
