Thats exactly why AFCIs were created. After it was theorized that 75 amps could be seen at the end of a really long run a 75 amp pickup breaker was created as a concept but soon realization came that certain goods would trip it.
You lost me a little with that post. AFCI, s were created to detect arcing? No?
 
They are trying to bring it in, but when common sense prevails, they'll either reject, or make sure the they are not cost prohibitive
Oh, that's all right then, because common sense always does prevail whenever they get into law-of-diminishing-returns territory, and they always carry out comprehensive cost-benefit analyses....

There is no cost benefit. They are just an empty fire extinguisher. EFLI and plug fuses provide 100% parallel and earth arc fault coverage. That leaves serial events, where arcing is the end stage of joule heating assuming combustion has not already started. 90% of all electrical fires start without any arcing.
