      db.createCollection( "x2")
db.x2.stats().systemFlags
//db.runCommand({collMod:"x2",usePowerOf2Sizes:false})
db.runCommand({compact:"x2"})
db.x2.stats().systemFlags
      Show
      db.createCollection( "x2" ) db.x2.stats().systemFlags //db.runCommand({collMod: "x2" ,usePowerOf2Sizes: false }) db.runCommand({compact: "x2" }) db.x2.stats().systemFlags

      The symptom is that:
      When compact is run, the systemFlags bit is set to 0.

      I believe it is because in
      collection_compact.cpp

       Status status = _indexCatalog.dropAllIndexes( true );

      leads to
      index_catalog.cpp

                  _details->clearSystemFlag( NamespaceDetails::Flag_HaveIdIndex );

      But then it's never re-set for the rebuild of the _id index again.
