A rushed, vibe coded update to a subtle algorithm that has not been statistically validated is not helpful. What's the point of this? Increasing the stack depth is easily done, and for all we know this update completely destroys the statistical properties. I don't actually care if it doesn't, the point is that we all have better things to do.
