      The cache for lookup can be enabled for $searchMeta. For standalone instances, this can be done similarly to the enablement of the cache for $search in SERVER-63816, by allowing the $searchMeta stage to bypass the NOT_SUPPORTED check. The sharded scenario doesn't work with just that change and seems to be more complicated.
