Knowing how to work with builtin tools would shine in that environment. I first learned this style in a Spolsky blogpost were they talked about Wasabi, a language that compiled to either PHP or Visual Basic I think it was, the idea being that those languages were preinstalled in most servers of the era.

In a similar sense, knowing how to work with the builtin tools of major OS is a huge advantage. If you can write your code in vim or nano or notepad without breaking a sweat over your favourite hotkeys not working, that's a lot of hours saved.
