Following SERVER-31763 and SERVER-30834, there are no longer any circumstances in which we forward a complete $changeStream pipeline from mongoS to a single shard. Since all $changeStream pipelines issued to a mongoS must now split and be merged locally, the HostTypeRequirement for all post-split stages should be changed to kLocalOnly.
