I agree that there's the danger of advice being taken as gospel, as you put it. FWIW, I don't ask that anyone substitute my judgment for theirs, and I don't by any means think there is One True Rule on how to go about things. The only One True Rule is: think about what you are doing and use your best judgment.
I simply felt that if I'm going to take a position in the meditation, it should be consistent. I wanted to offer food for thought, and so I presented my reasoning as directly as possible. As I've mentioned elsewhere, I've mainly been in situations where these arguments make sense: my systems don't get pushed to more than a handful of servers and accounts, and my organization's policies give me wide latitude to choose what software I need to accomplish the task at hand.
Someone else would be much better qualified to write the contrary meditation on
