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....

Seems as though Metrel believe AFDDs are going to become much more common...

You kidding? The trojan horse emptied its contents:

The goal is 7 billion people living with AFCIs.

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.
