      db.getFieldTest.aggregate(\{$project:{o1:{$getField:{input:"$_id", field:"x"}}}})
{ "_id" : ObjectId("66e8738aee1179b743aff3cd") }
{ "_id" : ObjectId("66e87391ee1179b743aff3ce") }

      All non-objects seem to lead to same outcome.  Design doc said:

      The ‘input’ argument is optional and defaults to $$CURRENT. A query fatal exception is thrown if it evaluates to anything other than missing, null, undefined, or Object.
