Is RR 2.0 "doomed?" My impression is GK considers it extremely successful. Do devaluations necessarily foretell a death knell?

Even if we suppose RR 2.0 is doomed, imagine that from introduction it had been a simple 10 points per dollar across all fare classes, for both earnings and redemptions. Also imagine there had been no 50K signup bonuses making CP so easily in the grasp of so many people. Would we be seeing such early devaluations? A program like would have been even more boring than RR 2.0, and probably far less successful by GK's reckoning, but would it have been unquestionably "doomed?"

It is said that bad facts make bad [case] law. I'm not yet convinced the answer to the query posed in the thread title is "Yes."

Thanks for this refreshingly thought-provoking thread.
