Is Alleyne a stare decisis sleeper about "super-duper precedents"?

Last month the Supreme Court granted cert in Allen Ryan Alleyne v. United States, in which the questions presented is simply "Whether this Court's decision in Harris v. United States, 536 U.S. 545 (2002), should be overruled."  Because Harris is, of course, one of the holes in Apprendi jurisprudence, hard-core sentencing fans and Sixth Amendment gurus are jazzed about what the Alleyne case might mean for the division of responsibilities of judge and jury in criminal justice decision-making.

However, the notion of whether Harris "should be overruled" has me thinking Alleyne could be a sleeper case concerning the doctrine of stare decisis in constitutional law and practice.  Significantly, Harris did not create the constitutional rule that legislatures could allow sentencing judges to find facts by a preponderance of evidence to trigger the application of mandatory minimum prison terms.  Harris merely reaffirmed this constitutional doctrine in 2002; it was established back in 1986 in McMillan v. Pennsylvania (and the McMillan opinion suggested its holding was just a reaffirmation of constitutional rules first set out in the 1949 case of Williams v. New York).  In other words, Harris is not just a regular precedent: like Roe v. Wade and other controversial rulings often challenged and often reaffirmed, the constitutional doctrines allowing judges to find facts to trigger mandatory minimums arguably qualify as a "super-precedent." 

As some may recall (and as highlighted in this Essay by Professor Michael Gerhardt titled "Super Precedent") the idea of super-precedents has been sometimes espoused by defenders of Roe.  Indeed, with Roe clearly in mind, then-Senate Judiciary Chairman Arlen Specter asked then-SCOTUS-nominee John Roberts during his confirmation hearings whether he agreed there were "super-duper precedents" in constitutional law.  Though I do not fancy myself enough of a constitutional theorist to know whether super-precedents do or should exist, I do know that Alleyne tees up consideration of this idea perhaps as well as any case in recent memory.
