Recently in the review queue I have seen a number of questions which had they been asked today would be off topic because they specifically refer to an end of life version of Ubuntu but were on topic when asked and have accepted answers.
Should these questions be closed as they are no longer relevant to any supported version of Ubuntu or kept open for historical reasons.
I've been selecting "skip" so far but I can see arguments both for keeping and for closing and presumably eventually deleting these questions.
Do we have a policy on this and if so what is it?
