Auto kill long-running PSQuery?

What are your thoughts about having a script that automatically kills SQL run by PSQuery that runs beyond a certain duration?

Love it/done it
Like the idea, never done it
No opinion
Make me nervous
Never

@Charles-Benson I like the idea, never done it.
I'm not a query expert but it gives me pause. At the very least I would wonder if killing sql related to a psquery would have any affect on how Query Administration sees the query. I also wonder about a time that would work for most queries unless you're thinking about duration of an hour or more. Those might not be issues.
