Such a close reason might be a nice feature to have, but remember that many times the questions can be edited and made independent from the current events, see for example how this sequence of edits saved this question: http://aviation.stackexchange.com/posts/13533/revisions.

So, in conclusion my opinion is: yes to the close reason, but let's use it only if effectively necessary.
