I think the point raised earlier that Capone was more or less cammorra which didn't have the making ceremony the sicilians did and capone's cammorra defeated Aiello's Unione Sicilione. I think it makes sense that Capone and his successors wouldn't think much about implementing the sicilian tradition of the making ceremony. The defacto head of the national commission, Luciano, didn't care much for the old traditions either so it's unlikely he would have encouraged chicago to start doing that.

When the sicilians loyalists in chicago eventually merged with capone's outfit, maybe at some point they curried enough favor in the organization to have a ceremony, but following the lineage of the hierarchy in the outfit, it seems unlikely they would have a ceremony.

...Accardo was from sicily so maybe he started the ceremony if there is/was one

Someone said Nick Calabrese said they had a ceremony like in the godfather movies, there were no making ceremonies in the godfather movies. is that what he was getting at?
