Hmm, I didn't see that mentioned in the docs. It makes a difference to

But regardless, this would be the same potential behaviour change I
mentioned. (In the actual docs, it should probably be explicit about

might not *think* they were lying, just that they hadn't sorted the

Still not convinced this is safe enough to be worth it ;-)
