Electronic ignition upgrade

Very true on the points systems. Also the only reason for dual points was to make up for the weak spark of a single pount setup. This was a stopgap crutch before high energy electronic setups. GM did it right with their design of HEI by ditching the ballast when they went electronic as it was no longer needed to prevent point arcing IMHO. Even fords duraspark electronic remained hobbled by a ballast.

I'll disagree with both of you. Electronic's original advantage was reduced maint, most important with fleet buyers. Dual points advantage is about being effective over a wider rpm range. Meeting emmissions was a big driver in the adoption of various electronic systems in the 70s. They remain more consistant over time and can be designed to help light off a good burn under more difficult conditions, such as added exhaust dilution.
