 > We are not checking that xz is used in the generated incrementals as
 this would require extracting them again after they are created. But we
 are using the `mar-tools` from the new version, and `MAR_OLD_FORMAT` is
 not set, so I think it should get used.

 After manually extracting one of the generated incremental, I see that the
 files are indeed compressed with xz.
