While FairIsaac has developed a new scoring algorithm referred to as FICO 08, and is now marketing it to some extent. the old (current) algorithm is still in effect. It is up to their customers to decide whether or not to lease and use it. The three CRA models are based on the old algirthms, which incude scorng for AUs.
FairIsaac also develops and sells market-specific algorithms, such as those for mortgage lendors. If a particular creditor doesn like the inclusion of AUs in their credit evaluations, they coulod decide to switch over to FICO 08, but I have seen any reports of this being done. It is no all or nothing.
