Mel and Walt, look at their signatures. OK. Yes AC are more advisory not binding (but they are note below). Of course there are debates, because internet and:
1) FAA on occasions does not understand or is consistent with their own "Orders". FAA Inspectors (and DAR's) follow these Orders fairly well, but stuff happens. Things are indeed subject to (legal) interpretation. So debate might be educational, or find an error regardless of who made it. FAA can make mistakes.

2) Yes AC's although not binding, informational, educational, clarification, CAN BE interpreted as law in Court. There are infamous cases of pilots violated for not following an AC or AIM missive, or shock of shock actually violated following an AC.

Catch 22. Bottom line AC's, AIM are "official", recognized by authority.
3) AIM is not regulatory like an AC, but both are "Regulatory in Nature". Meaning it is written down and they kind-a, wanna, u2, follow it (unless they don't). I know of violations of a pilot for not following an AC or AIM recommendation. Although not regulatory you will be slapped hard. Judges put a weight into these Docs.
4) The only person'(s) opinion that matters is "The Administrator" and their Lawyer's and Federal Judges in DC. The FAA's own Lawyer's and Fed Judges at times disagree with how FAA interprets their own regulations, orders, etc. So they get their hand slapped, which sometimes causes a kerfuffle for GA, Airlines and Manufactures.
5) Data Base, records, are handled by bureaucrats (not meant as a pejorative) in Oklahoma, entering the paper work they are given (I say with sympathy). They don't make the rules, just manage the records. If something is glaring I am fairly sure they flag it. Subtitle nuances, issues like this is not their concern, responsibility. Garbage in garbage out. I am sure they have QC, error checking, checklist, trained, but... Overall I think OK records does a great job.
In the end no one is going to get hurt but someone's feelings may be, which I understand. You spend many years and dollars building a plane, flying it, you want your name as manufacture. All I know, I got my name as manufacture on an RV-7 a year ago or so. The friends RV-12iS registered before min by a year or so, an E-LSA does not show him as builder. Looking at that ORDER after talking to local FAA (had to go through 2 Inspectors to find one who knew what was up) that is correct. So no argument. "I was only following orders". I prefer the
Sergeant Hans Schultz defense: "I know nothing! I see nothing! Nothing!".
