+The Working Group is currently seeking implementer feedback with respect to the
+usefulness of bitstring entries that have sizes greater than one. The
+approach adds complexity to the solution and its not clear if there is
+enough of an implementation community to support the feature. The WG is
+considering three options 1) keep the feature, 2) allow the feature to be
+optionally supported, and 3) remove the feature. At present, the specification
+implements the second option.
