Just saying, not sure this has been posted before.
Players that are masters at playing variants like atomic, crazyhouse, horde should get some
recognition, although this is a very small thing. I think it would be a nice addition.
Example a crazyhouse GM would be ZGM, an atomic GM would be AGM. (Lower ratings would maybe be ZCM, ACM etc) I believe they used to have a title for players who reached 2200(Lichess master?). Now, I don't know what the requirements for it would be, I don't think I am qualified to say. Just a thought. (This would NOT overwrite normal chess titles. It would be regular chess instead of the variant or beside it.)
