There are a great many questions about the 5th edition of D&D that were asked prior to the release of all of the core books. Some of those questions are now outdated, since additional detail is available in the DMG.
For better or worse, these outdated questions have accepted answers. As a result, it can be challenging for an updated, accurate answer to rise to the top in votes and replace the accepted answer.
So what is the preferred approach for reconsidering such questions? Is it a good choice to post a near-duplicate question, such as "Now that the core books are released, original question here" or is it better to respond to the original question and hope that the updated answer eventually trickles up to get some attention?
Is there a tag that could be applied to questions where the accepted answer states "We'll know more after the DMG is released" so the community can more easily identify questions that may need to be revisited? Perhaps dnd-5e-basic?
As a concrete example, consider this excellently-answered question: Does a single PC who is stealthy get to surprise monsters when the rest of the group is not?
The answer is well-authored, clear, concise, and helpful. It is probably the case that this answer is still correct. Its only fault is that it predates the core books, so the viewer cannot be confident that it is correct in 5th-edition as currently written. The answer would be more useful to current audiences if it were updated with the appropriate page numbers and citations from the PHB and DMG rather than the starter kit.
I would hesitate to post my own solution, as it would be merely a restatement of the already-excellent-and-accepted answer with updated page numbers and whatnot. While I currently lack the reputation on this Exchange to edit answers, I would still hesitate to do so, as changing the page numbers and updating the citation text as necessary is, in my opinion, too substantial a change to be made in the pure editorial sense outside of a community wiki.
