On Debian based systems /dev/ptmx is 0666 root.root. But the gid of tty is already supplied for devpts.

Hmm. Several possibilities: - Change the filesysteme name and the old name remains usable with /dev/ptmx. Problem: You could mount the filesystem with the old name within a container. - Make the first mounted one special. Problem: Will not survive a umount/mount cycle. But this would be not the case anyway.
But you are sure, none of them is a pretty solution.
