Given a Z-13/8 architecture, what is the point in making the SD-8 self

Yes, interesting question.
If the battery is functional, no need for the self-excitation circuit. If the battery is not functional, the alternator is likely to quickly trip out with overvoltage?
Perhaps a depleted battery (shame on me for having such thing) can serve as a damper?
