I have noticed that when adding a new question on Puzzle Stack Exchange (PSE), one may sometimes see the warning:
The question you're asking appears subjective and is likely to be closed
Similarly, when posting a puzzle that is concise, for example, like this one, one may see the error:
This question body does not meet our quality standards. Please make sure that it completely describes your problem - including what you have already tried - and is written using proper grammar.
I can understand this makes sense for most forums on Stack Exchange, but in light of this recent question about whether puzzles as questions are appropriate on PSE:
Yes, it is absolutely acceptable to ask [puzzle questions as opposed to methods on solving them]. Originally, PSE's main focus was supposed to be questions about puzzles. ...When PSE started having a lot of actual puzzles as questions, there was a good deal of soul-searching about whether that was appropriate...
I can see no reason for why short "questions" are necessarily low quality. Many puzzles I've encountered are succinct in length and receive overwhelmingly more upvotes than downvotes (if any).
A similar question about the warning/error message was asked here, and the consensus seems to be that such questions are "essentially ... very low quality". However, that question was nearly 6 years ago.
Based on the response above, it seems such questions are now more acceptable. So, is it time these warning/error messages were updated to reflect the direction that PSE has taken (assuming that it is possible - maybe these are inherited by some SE template and cannot be easily changed)?
