When mag coils were no longer hand wound and they started making the coils on computerized machines and encasing them in plastic a whole batch of bad coils could get put out there and the warranty problems got worse too. A tractor with an engine properly broken in and in good shape can be less sensitive to individual components. In my opionion there are very few new mag coils made today that can even stand up to industrial 24/7 use and why many go with other means of power now also.

Early resistor plugs used a carbon type core inside the plug between the metal rod cores to suppress the ignition noise with radios. The decreasing insulation resistance of the insulator tip results in an occasional failure of ignition. This does a nice job of burning off the deposits that accumulate on the plug in the "lazy" cylinder. Those elements can reduce radio interference but are an added and unwanted load on the low energy ignitions and waste energy in the form of heat and I squared R losses versus discharging all the stored energy across the plugs gap where its needed the most.

You are correct about the autolite book and web site both cross the D23 to the 388 and it also says they are resistor type. Autolite 388 and 386 are resistor type and NOT recommended for mag use although suppliers will tell you they cross to a D21 do NOT use them on a magneto! A consequence of these combustion deposits on the insulator tip isreduction in electrical insulationresistance accompanied by failing ignitions and after a certain period of time even by a failure of the spark plug performance.
