Pending completion of SERVER-78144, Bonsai and Stage Builders will each have a different method of populating the shardFilterer slot in the runtime environment before executing an SBE plan. The latter uses a MultipleCollectionAccessor, whereas the former does not have one and does not support that functionality. As part of CQF, these two methods/code paths for constructing the shard filterer should be merged.
