      implicitDefaultWriteConcern = if ((#arbiters > 0) AND (#arbiters >= ½(#voting nodes) - 1)) then {w:1} else {w:majority}.

      We should keep track of the implicit default write concern in ReadWriteConcernDefaults. _getDefault cannot return the implicit default write concern yet however (that will happen in SERVER-55703), since that has implications for sharded clusters that we have to resolve first.
