Thanks. It just occured to me to ask if we should backpatch it.
The goal is to avoid someone trying to use this as a peformance option.
It's to their benefit and ours if they don't do that on v10-13 for the next 5
years, not just v14-17.
The patch seems to apply cleanly on v12 but cherry-pick needs help for other
branches...
