"Tail latency has improved by YMMV for everything else" => yes, I think that's a valid (but conservative) read. Of course, in many (most?) applications, tail latency is very important. Tail latency also tends to be the thing that optimizer engineers target (i.e., reduce the runtime of the longest running query).
