Even, if and when, FICO 08 is released,and includes a provision to delete AUs, it is NOT automatic that ANY lendor will just jump on the new FICO product bandwagon. FICO 08 will not supplant all prior scoring algorithms. FairIsaac will still deliver to them what they decide to pay for. The current algorithm will not simply die. FairIssac has released other "improved" algorithms in the past that were simply not embraced by their customers, and died. Lendors, comfortable with the old algorithm, will take a long time to supplant the unknown "new" shoes when their old "work" shoes are not creating blisters.
So, I agree. History has shown us not to knee-jerk with each release of FairIsaac,and I would not delete any current AU status based upon an unknown and unaccepted fairyland of FICO08.
