I'm going to disagree, for a very specific reason: There is no way to retract a moderation vote.
This means that there are cases where I initially think a question is unanswerable, but later find a way to reinterpret it that lets me answer... but am stuck either violating this guideline or being unable to post my answer.
The only fix the system supports is to vote to re-open if it does get put on hold. Which I'd do, but which doesn't look as nice.
Similar problems arise if when voting to close I accidentally hit the wrong reason; I can't fix that.
This is a SE design problem, and isn't something we can address in this sub-meta. It should probably be raised in the main meta... But to be honest I haven't seen enough real trouble caused by it that I'm interested in making that effort. If someone cares enough to want it fixed, they can and should take it there.
(By the way, reopen appears to be one of the features the Android app is missing; I had to flip over to browser.)
