Not sure... how likely is it that people will be contacting servers
which are running a version of rsync even older than Debian Jessie?
FWIW, the original bug report: https://bugs.archlinux.org/task/41024
rsync already spits out an error stating the remote machine does not
understand the relevant option:
"rsync: on remote machine: --new-compress: unknown option"
So this seems like an obviously debuggable issue -- and the solution is
just "upgrade your remote server". It doesn't stop you from using ssh,
scp, or rsync without compression.
