What's the general way of dealing with questions, that do not and cannot have a valid answer, because of for example the issue in focus is an unresolved bug (possible example here). Should one still accept an answer ("It is a bug.") or just wait for an indefinite time until Wolfram Research fixes it? I understand that there might be a concern here (on SE) as unanswered questions hinder the site's statistics. So it might not be a good idea at all to post assumed bugs. Opinions?
I think the answer "it is a bug" (when coming from a trustworthy source, e.g. WRI employee) should be accepted in cases when a given function and / or its specific use is the main focus of the question, and work-arounds aren't what the asker wants.
The reason I think so is that this will be more useful for new users. Once they are directed to the question, they have a concrete answer, so that they can move on, decide what work-arounds are acceptable to them, possibly ask further questions etc. Seeing a long-standing question without an answer is quite frustrating.
