We never used it and don't have any plans to use it going forward. All conceivable parts of its functionality that we might use going forward have already been subsumed into allocation tokens, which are a simpler way of handling the same use case that are also standards-compliant. Also gets rid of the hideous ANCHOR_ prefix on anchor tenant EPP authcodes that was only ever necessary because of overloading the authcode for anchor tenant creation. Going forward it'll be based on allocation tokens, so there's no risk of conflicts. ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=209418194
