Ok, I'm happy with this now that I was reminded of the difference between clusters & chunks. :/ Ben, regarding your compat concern, I agree w/ Dave that there should be no failures moving forward or back; as he & I mentioned (I had missed his other reply), the kernel already (used to) set different cluster sizes based on the memory available in the machine that mounted the filesystem.
