      Write commands that take 'let' parameters should ensure those expressions are evaluated once, instead of once per shard. For example, in a multi-update you should be able to use {let: {r: {$rand: {}}}} to pick a single random value and use it consistently when updating each document.

      SERVER-75927 fixes this for the 'find' command.
