To be honest, I'm still trying to parse this last sentence.

Working harder won't help. I just need more time to think about this. I
don't know if you saw the documentation and code required to deal wih this
issue in version 1.32 but it was very messy. I invested effort which I
believe resulted in a major improvement. So far no one has come upon this
in practice and I'm curious to know why that might be.
