Description

I've noticed that the documentation at https://docs.mongodb.com/manual/reference/operator/aggregation/lookup/#use-lookup-with-an-array says on using $lookup with an array as local field:

"If your localField is an array and you’d like to match the elements inside it against a foreignField which is a single element, you’ll need to $unwind the array as one stage of the aggregation pipeline."

This is no longer true since SERVER-22821 was fixed a while ago, isn't it? AFAIK you don't need to use $unwind anymore to join an array as local field against a single foreign value.
