It seems to me that this kind of information is almost impossible to capture in a single answer. The question Do I need a visa to transit in the Schengen area? just appeared with a huge wall-of-text answer. It's comprehensive, but doesn't immediately provide answers. And it's probably intimidating to non-native English speakers (the vast majority of people who actually need a Schengen visa fall into this category).
Do we really believe that people who need to ask this kind of question will be able to find this comprehensive answer? And if they do, will they be able to navigate the answer to determine which parts of it apply to them?
Will we (the answerers) close all "do I need a Schengen visa" questions as duplicates, and point to this super-answer? If so, I'm afraid this won't actually provide an answer to the questions people actually ask. If not, then what is the point of the super-answer?
I'm not a supporter of this kind of general artificial question-answer pair. There is certainly value in specific artificial question-answer pairs, I've added my share of those to sites around the SE network. But questions where the answer is multiple pages long would normally be closed as "too broad", if they weren't already answered by the asker.
