This would answer my question, if only it had a real, accepted, useful answer, which is why I ask.

I encountered this item in the VTC Review Queue. Essentially, it's a case of a question from 2011 being closed as a dupe of one asked yesterday.

I understand why this has happened. Indeed, there are plenty closey votes on the old Q, and it's probably for the best, but I wonder if we have a policy on this.

I don't intend to challenge Mego or the close-voters by asking this question here. I intend to understand more clearly under which circumstances this sort of retro duplicate identification is good or common.

This question pair I cite in particular does have a discussion, which is helpful to me, but I want to know about the broader scope of all questions, not only a restrictions-differences-semantics centered discussion.

When is it appropriate to close an old question of a dupe as a newer one?

I don't believe the two questions are duplicates really, because I think that their separation of intent and time is enough. (This is not reflected by my vote to close, which I cast when I had a different opinion about this 20 minutes ago.)

    \$\begingroup\$ This is absolutely a dupe of the linked discussion. If there's not a clear consensus, either a) write your own answer, b) try to bring attention to the lack of consensus in other ways, or c) accept that it will be judged on a case-by-case basis. \$\endgroup\$
