That's pretty interesting. Is there a concrete example of a quorum definition where the probability of an outlier is improved vs majority quorum? I'm struggling to come up with one. I've always assumed majority is optimal, since you can tolerate outliers in (n-1) / 2 voters without seeing an outlier for the commit overall. Eg: for 3 node Raft - you'd need both followers to have an outlier before a client notices a slow commit.
