You just went and used some archaic terms, and may well have lost many of the magenta children from this discussion.
The FOM requires us to use LDI & FD for SID/STAR (or equivalent navigation map display) for lateral guidance. But the use of A/P is only recommended, not required.

That said, people have been flying CDI's for a long time. If the line is in the center you ARE on course, it's not about a little airplane and a white line. Again, I'm fairly confident I can keep a CDI centered.
