A raw number across the whole federation would be useless. Different instances have their own cultures, making a unified number worthless. People could also goose their numbers by creating an instance that gives their account unlimited karma.
Instance karma could be useful, but it is a design decision not to show it. I suspect that will continue until there is a need to use karma for moderation, but I suspect that defederation would be the lower lying fruit for now.
