I think we should lighten up.

If it's otherwise on topic, we should allow it. We should not force people asking a question to clear the burden of "practical". And, an "actual problems that you face" can be anything that you want an answer to pertaining to the subject matter. How do you differentiate between

• An "actual problems that you face" in a question you want an answer to.
• Not an "actual problems that you face" in a question you want an answer to.
