> Any objections? Yes, I object. "xz" is not sufficiently well spread in default system installations yet. Use "bz2" if you must change. That gives better block robustness. Changing for size reduction is a questionable motivation. Changing just because others have done so is even worse.
xz is spread enough within the GNU project more so than bz2, and some projects have stoppped distributing gz tarballs completely. But as compromise, since your objection is immensly valuable, lets distribute both gz and xz tarballs.
