      pipeline: 

      [{$match: {x: {$all:[]}}}, {$replaceRoot: {newRoot: {y: 42}}}]

      produces the following stage:

      {
        "$_internalUnpackBucket" : {
                "include" : [ ],
                "timeField" : "a",
                "metaField" : "b",
                "bucketMaxSpanSeconds" : 3600,
                "assumeNoMixedSchemaData" : true,
                "eventFilter" : {
                        "$alwaysFalse" : 1
                }
        }
},

      That is, it's possible to have no fields included and an event filter with no deps.
