YAFQ - Yet another FAQ Question - Setting up a topic based FAQ?

So there have been a number of questions about adding a FAQ feature to SO. For instance:

Setting up a FAQ for the C++ tag

There are a lot of good arguments there, and I don't want to rehash them. My question is more about what we SHOULD do if we want to organize a topic based FAQ.

Of course there is the Frequent tab in the Question search, but this is decidedly more needle-in-a-haystack than a true FAQ. What separates a FAQ is that a FAQ is curated, while an arbitrary search for frequently linked items is much more noisy.

As I see it, there are several possibilities in the given system.

1. A single Topic-FAQ wiki-question. This has the advantage of "all FAQ questions in one place"
2. a topic-faq tag, such as the C++-Faq. I find this to be less useful because it doesn't allow commentary by the curator to be associated with the list of items. Additionally, it's a lot more work to monitor for tag abuse than to watch a single question to prevent non-faq questions from being added.
3. Both 1 & 2 above? Seems like double the work.

Would it be wrong to just go ahead and create #1 and let it evolve? Or would this be considered off-topic (or at least inappropriate for SO itself, would a topic-based FAQ belong better on meta?)

Obviously, a FAQ can also be considered too opinion based, so that is also an issue. Lots of people get worked up about what should and shouldn't be a FAQ.

It would be nice if SO had a feature that would allow questions/answers to be limited only to moderators and those with badges in the topics tagged by the question. Even better would be tags that only moderators/topic-badged can add, thus a question could be tagged 'topic-faq-proposed' and a moderator/topic-badged person can change it to topic-faq and not have to worry about random people marking things as topic-faq.

In the absence of any "curated" topic support in SO, what is the consensus about creating FAQ's and the most accepted way to do it?

EDIT:

Seems like much of what i'm looking for can be accomplished with the tag-wiki, a function which I didn't even know was there. The term "info" is a bit underwhelming for discoverability of FAQ's though. But that's ok.
