Log drivers are instantiated on a per-container basis, and passed the container ID (along with other information) when they're initialized. Drivers that care about that value are caching the value that they're passed when they're initialized and using it in favor of the value contained in Message structures that are passed to them, so the field in Messages is unused, so we remove it.
