There have been a fair number of architecture questions, and I expect most of them have been subjective to some degree, as many tags, e.g.
game-design, will be.
Is there an existing policy to discourage best practices questions in general? Is there a policy to discourage architectural questions in general?
If so, Isn't this is a severe blind spot in the knowledge we try to impart? Is this really worth enforcing when architectural concerns are so crucial to the way we implement projects? From experience teaching, coding details are considerably less important in the long run than the ability to teach overarching approach / philosophy / methodology. Many of us have had answers in this vein from teachers, professors, lecturers who gave us lessons that would go on to last a lifetime.
I'm a firm believer in the concrete, and SE encourages questions that can certainly be answered, which is good. But to kill questions like these off the cuff, seems supremely short-sighted, assuming that's the policy.
