If the bot can smoothly backport these, let's do so, otherwise not bother.

Sorry, @peterjpxie and @hugovk, I could not cleanly backport this to 3.11 due to a conflict.
Please backport using cherry_picker on command line.

Sorry @peterjpxie and @hugovk, I had trouble checking out the 3.10 backport branch.
Please retry by removing and re-adding the "needs backport to 3.10" label.
Alternatively, you can backport using cherry_picker on the command line.
