Yes, I suspect you’re personally the one who is hit the worst by this.  I’m super sensitive to that, because I really really really want to make sure that releases are smooth and successful.

That said, are you aware of Rui’s work on lld?  He developed a process in which people with significant out of tree patches were able to catch up, merge the mega patch and move forward without significant churn.  I agree it is non-zero, but it is very low, and the cost seems worth the price of forward progress and avoiding perpetual stagnation.
