xz has slow compression, fast decompression.  You're not really going to
build packages on any box where compression speed is a blocker, and even if
you do, actually building the package will take a wolf share of the time.

On the other hand, quite a few users will _decompress_ stuff on terribly
underpowered boxes, and xz shines there.
