Reading [Note 8] suggests that with DDE forward/backward sync via other
means than command-line arguments is meant.  If that's the case, then
AUCTeX does have support for that with certain viewers, e.g., AUCTeX and
Evince and its derivatives such as Atril communicate via DBUS (if
available), AUCTeX and pdf-tools communicate directly via Lisp.
