Elsewhere in this maze of threads Arnd claimed to have tested the benefits of metadata compression - and it making little impact. My guess is that it would make a large impact if metadata would be a significant part of the filesystem image. Usually metadata is close enough to 0% to be mistaken for statistical noise. So compressing it makes a significant impact on an insignificant amount of data.
