I have a question regarding a question which was closed as off-topic in February 2018, because it revolved around a development version of Ubuntu (18.04).

Ubuntu 18.04 has been released since, and after that point I received at least two up-votes for my answer. From this I get that this problem still persists, and - if posted now - would be a valid question.

So, off-topic questions concerning a development release can become on-topic, just by the passage of time. What are the rules here? How and under which circumstances should they be re-opened?

I think right now questions like this just stay in this dormant state, with some probably sub-optimal answer and little possibility two improve or discuss problems.
