Hope of hopes here is that we don't just transition when an alg is broke. Algs weaken over time - that's just a fact. When we retire an alg because it doesn't cut it anymore, then running with the old unbroken alg is a downgrade but assuming the alg ain't broke then it's probably okay for the transition period. spt
