IMHO it very clearly isn't - the OP identified a particular usage pattern and asked about it.
Yet it has already gained four 'close' votes and so is perilously close to getting closed, even though the question itself has 17 upvotes and my (accepted) answer has 23 and counting.
This suggests to me that those voting to close it are not applying due diligence.
Given just how many 3k+ rep users there now are (>5500), should perhaps that threshold be raised?
EDIT ok, it did get closed and re-opened again. I wonder whether the exposure of the question here on meta contributed to the rapid reopening. I expect it did, since the votes on the question also jumped after I posted this question. [and no, I wasn't rep whoring, as I hit the rep cap today already].
However, since the closure revealed who had voted, and therefore their reps, we can see that they were 33k, 10k, 8k, 7k, and 5k of rep. The 8k user was the one that posted the original (IMHO incorrect) close vote, but there's no way to revoke a close vote.
I don't know whether those numbers support my original assertion that the rep threshold may be too low. I'm inclined to think they don't.
