I am not sure just when the ISAF decided that only they had the right to ordain the usage of the word Worlds, but they have enforced this before and recently. I wish I could remember what classes or boats they refused that right to, but I do remember seeing this issue come up before. I am not a fan of these organizations, but MarkMT is right. What we need to do is to participate and gain visible representation within these groups and get in their faces about the needs of multihull sailors. Until we come together and demand a say in our future, we will always get the short shrift.
