Preemptive insurance against duplicate-item proliferation when more metals-producing mods are added (e.g. when Power Grid lands, or any future Mekanism/Thermal/etc. addition). Today's pack only has TFMG as the metals provider so AU is largely a no-op now, but ships with sane default tag preferences that activate automatically as duplicates appear. Tiny mod (~290 KB jar), client-optional/server-required per Modrinth.
