Good picture n fun discussion, My only comment concerning those tandem ballast resistors would be they are fine for the coil, but most of those ballast resistors are ONLY like 1 to 2 ohms, while the 10 ohm resistor or the idiot light (maybe 40 ohms) are much higher.

That all being said, Ive seen plenty of those alternator set ups WITH NO RESISTANCE WHATSOEVER (or a diode) and they all worked fine NO PROBLEM. Its my belief HOWEVER the idiot light or 10 ohm resistor or more can provide some degree of current limiting protection for the alternators internal circuitry which no or low (1.5 ohm ballast) resistance does not.

I guess THE BOTTOM LINE in my humble opinion as far as safety and to still allow the alternator to excite would be in order of these preferences:

BEST INCANDESCENT Idiot Light of around 40
ohms or so cuz it limits current PLUS
is a charge indicator

SECOND BEST A resistor of at least 10 ohms up
to maybe 40 to 50 or so ohms

THIRD A diode to prevent run on

FOURTH To use NOTHING

Any agreement or disagreement ????????
