It seems redundant to point out that some transactions are only relayed 
by a subset of a node population if there are multiple diverging mempool 
policies with significant adoption.

However, I concur that Bitcoin Core should match its default setting for 
`mempoolfullrbf` to the behavior of miners, and there appears to be 
palpable evidence that a supermajority of the hashrate has enabled 
`mempoolfullrbf`.
