SLES ships with and supports xz.  It doesn't ship lzip.  Source rpms may
have their tarballs compressed with xz and it looks like rotated logfiles
get compressed with xz.

Not shipping xz to users is likely not an option given its wide-spread use.
Not using xz compression but sth else itself might, but I do not have a strong
opinion here.
