A kernel library will say it has the newest language version if no language version is set. This basically preserves the current semantics of always being on the newest version (if nothing is explicitly done), e.g. if creating a kernel library by hand and not setting it. The front_end also utilize this and just doesn't set it, if it isn't set.
