There are some question-answer pairs where X poses a question and a few seconds later answers it extensively, such as this one (fair use), this (SCOTUS ties). I think more than one person has contributed such q-a pairs. I understand there is no direct SE mechanism for constructing a topic-specific FAQ, but the effect could be achieved by linking to such questions in a single Meta question, which could then be prominently mentioned somewhere in the help center (to encourage people to actually read those answers). Does such a thing already exist, or can it be created?
To put a slightly finer point on the question and develop the suggestions by @feetwet, is it possible (for the mods) to modify the on-topic entry in the help center to direct users to one or two sacrosant (locked) posts on Meta, with suitable verbiage indicating what good they are? I recognize that many people don't bother to look at the help center, but admonitions to do so might have greater impact if there was a central repository of information identifying the good and the bad. "Possible" in consistent with a policy answer "We really don't want to get into that", so I don't just mean "physically implementable".
