Why are system-namespaces not copied?

the man page states

    For systems that support extended-attribute namespaces, a  copy  being
    done  by a super-user copies all namespaces except system.*.

That's the reason why NFAv4 ACLs are not copied as they are in the
system.nfs4_acl (or system.nfs4acl) namespace.

Why are those namespaces excluded?

Not being able rsync ACLs von NFSv4 is a major drawback now that
NFsv4 becomes standard oder v3 and ACLs are getting more widely used.
