OpenARC Milter - Axigen integration

I was pretty surprised to not find any posts pertaining to Axigen integration with OpenARC, or even a sin gel post of somebody using OpenARC. Are folks just not using ARC headers? If anybody has any experience with OpenARC + Axigen, I would love to better understand if Axigen can be integrated via milter to OpenARC (or any ARC header milter).

Thanks.
