One can do both, as appropriate to the situation. For anyone who doesn't RTFA, it's not a new variable you set and then hope and pray people respect it (like on the Web), it's a proposal to standardize already existing variables that the tools provide for this purpose. The decision to use/not use the tool is often out of the developer's hand and is a business decision based on many factors. So if you do end up stuck with the tool, it's better to have a single predictable interface for this rather than hunt down the configuration every time for every tool.
