Well, if you are this principled maybe. But do note that we dont really ship suid binaries (except one binary with fscaps which is systemd-detect-virt), and hence by leaving systemd in the image without running it should result in no increased attack surface that wasn't there anyway... Dead code in the image, that cannot be use to acquire new caps isn't much of a security threat...
