I think that questions of this nature that ask about how to use the glitch from a gameplay perspective should be decidedly on topic. Wrong warping does necessarily require some understanding of the underlying code, unfortunately, to completely implement into gameplay and speed run routing. The gameplay and the code, in this case, are tightly coupled for this specific unintentional mechanic.
Once you get out of the realm of bugs that specifically help gameplay, then we're into trivia territory, and I don't believe that these questions have as much of a claim to live as gameplay-specific ones. I don't like them because they aren't practical or useful. I don't think your newest question should be on topic, nor should the NES question about sound distortion or the Pokemon question about why you can fish at statues. However, a Pokemon question about "Where exactly can you fish?" would be on topic, and could mention statues.
Questions that specifically ask for a coding-explanation for an in-game behavior with no gameplay impact should be off topic for our game-design close reason. Your question shouldn't have been re-opened.
Aside: Providing additional technical details on top of answering an otherwise on-topic question should also not be discouraged in any sense, but it is not required either.
- Questions about gameplay are obviously on topic.
- When a gameplay question requires a technical explanation, then that technical explanation is also on topic.
- General trivia questions are off topic, and should be closed.
