The bigger issue is . . .
Clarity.
My first "profession" was as one of the first 12,000 licensed paramedics in Illinois. I won't forget the first class, where the nurse instructor went on at great length about how the purpose of trade-specific language was to confuse, baffle, and otherwise shut out non-medical personnel from understanding what was being said. "All careers do it," she asserted.
Since then I've been versed in a variety of careers, everything from 'soup to nuts,' as the Brits say, yet the medical field is the only one where language is routinely use to lie, misrepresent, mislead, and confuse. Go figure. If you can't trust your doctor, who can you trust.

Let me correct that. Corporate America seems to consider it mandatory to lie like a cheap rug to employees. We don't have 'staff' and 'customers;' we have 'associates' and 'employees.' Etc.
The electrical trade is a shining light of clarity in this regard. Think back: How many of our heated discussions have revolved around what the code
actually says, as compared to what we thought it said?

Even so, it is a trade. You have to learn your ABC's before you can write your Shakespeare. Likewise, the codebooks are no place to learn a trade. You have to now what you are doing first; you need the context.

The FPN's attempt to put code sections in context. An illustration or explanation -- nothing more.
