It seems that the historical reason is that TCP_STRONG_ISS=2 impacted
performance noticably, especially in configurations with lots of short-lived
connections (i.e., lots of connection setups/teardowns). However, it's
possible that hardware has changed enough such that this is no longer an
issue. I think the issue is worth at least investigating.
