+The Working Group is seeking implementer feedback on these generalized selective
+disclosure functions as well as horizonal security review on the features from
+parties at W3C and IETF. Those reviews might result in significant changes to
+these functions, migration of these functions to the core Data Integrity
+specification (for use by other cryptographic suites), or the removal of the
+algorithm from the specification during the Candidate Recommendation phase.
