I guess they want to be able to make use of the data through a json.parse() command right away and they are not willing (at first) to make the extra step of using an extra library.

Yes, my use of the word "simple" was meant to convey that Group D

Can prefixes really be handled without a library?   I don't think so.

Agreed - an AC solution and a B (and D) solution.
