Well, of course, the original statute was replacing a bunch of State statutes or State rules, partly common law, partly statutory, that -- they had kind of a mixed up legal situation, and there was an interest in having one uniform rule for the first time around.
A single statute that could encompass other statutes and common law would hopefully reduce ambiguity and increase consistency. 
A bunch of 10-dollar words were thrown in that most people probably don't use so the AI might not be as familiar at working with them.
