I'm not an expert here, but because while let is a loop, it has to drop temporaries when it loops, so it must have at least one temporary scope, and empirically, the same scope includes the scrutinee and the body because the body can use temporaries from the scrutinee.

There is no edition2024 note because the behavior is the same in all editions.
