At my company, that means the plane will probably operate without an APU for several days.
To me, it's a risk management issue.
I read your first line and thought you were talking about keeping the engine running for a few minutes and pushing it that much closer to failing. Then I read the rest of the post.
So which would you rather put closer to failing? The APU or one of the engines?
Not that I think your way of rationalizing this has much if any logic to it due to maintenance inspection programs, but really, if it was actually that simple, wouldn't you want the crank up that APU and save the engine another 60 seconds of running?
