IETF has marked ARC as obsolete and recommended it's decomission.
[edit]3.6. Conclusions of the ARC Experiment Based on community experience and the direction of the DKIM2 work: The ARC experiment is over. Implementers and operators should not rely on ARC going forward, and should cease further Internet- wide deployments. Existing ARC deployers should plan to decommission them or confine their usage to controlled, intra- domain contexts where bilateral policy suffices. Experience from the ARC experiment is informing the development of DKIM2. The DKIM working group is actively developing DKIM2; relevant ARC insights, such as durable capture of upstream authentication state and intermediary handling, shall inform DKIM2 design where appropriate. RFC 8617 should be marked Obsolete. This document requests that the RFC Editor and IESG mark RFC 8617 as “Obsolete” upon publication of this draft (or its successor) to conclude the experiment and prevent new deployments.
