As far as Simano cogs are concerned, I imagine Shimano is thinking more about track racing.
Are Shimano cogs NJS stamped? Maybe I'm wrong but real track racers probably aren't using a cog larger than 16T. Shimano is the biggest giant in the component business and probably not worried about satisfying a few fixed gear geeks by making bigger cogs.
