So a key feature of the underlying thin provisioning needs to be
efficient tracking of a small sector size (which doesn't suit the
existing dm-thin target).  This compression target could sometimes
benefit from a larger block size though, particularly where the 
data above has large blocks.

(Could we name this something like 'microcompression'?)
