Yeah, it's not supported until OpenSSH version 5.x. That upgrade will
cause other surprises. Some colleagues ran headlong into it no longer
reading ".bashrc" unless it's an actual login sessin, and became quite
concerned when their local host-specific aliases were no longer
available to their remote "ssh" commands.

Yeah, I used to publish chroot cage tools for ssh-1, ssh-2, and
OpenSSH years ago.
