The question is whether it's better to have the complete previous version of the data, or 21% of the new version of the data.[1] And the answer is different in different cases, which is why atomic pretty much has to be an option (or a separate function), not always-on. But I think on by default makes sense.

[1]: In fact, with delete=False and a sensible pattern, atomic actually gives you the best of both worlds: the previous version of the data is still there, and 21% of the new version is in a tempfile that you can recover if you know what you're doing...
