While openSUSE has it, SLES does not. tar support seems to be

You mean SUSE Linux Enterprise Server is using a format that does not
guarantee safe interoperability among implementations[1] to "power
mission-critical workloads"!?

The decision to use xz was largely due to availability. If we use lzip
and 80% of the users have to fall back to the .gz tarball that would
be pointless.
For the case of SLES[2] I would say that avoiding xz is a must. IMHO
SLES users are better served by falling back to the .gz tarball until
the next major version of SLES is released than by suffering xz forever.
