Is it common for rsync to be missing?

Among the providers that offer SSH access, is it common for rsync not to be included?

In my past experience (with some hosts) I have always found rsync available. I just migrated to a host and asked about shell, but I did not specifically ask about rsync because I assumed it was a fact. It's pretty standard in Linux. I assumed he would be there if he had access to the shell.

It turns out that it is not available and I wonder if this is common and why. Is there a security problem or some other reason that you are not seeing?

Afaico I can not do anything worse with rsync than with having ssh already (they give freely) so I'm not sure why to block it. This particular host is CloudLinux / cpanel and my ssh is an imprisoned bash.

Any thoughts and experiences with this?
