I'm trying to figure out what's on-topic with regard to hypothetical questions. I know the global StackExchange FAQ discourages these (in so many words):
To prevent your question from being flagged and possibly removed, avoid asking subjective questions where … you are asking an open-ended, hypothetical question: “What if ______ happened?”
However, doesn't this rule out the bulk (or at least a large portion) of UX questions? Thinking about the questions I've read, answered, and asked, most of them could be categorized as "Suppose X, how could Y be accomplished/improved?". Strictly speaking, aren't these hypothetical? However, I assume it is not our intention to prohibit all such questions.
More to the point: All three of these solicit hypothetical answers to a real-world problem ("Well, you could solve X with Y"), so why were some closed as off-topic and others allowed?
