I can't stand incorrect indentation either, but my experience is that it regularly happens anyway, and I'd rather not have that break my code.

And "incorrect indentation" has a very different meaning when the indentation is purely for presentation: As illustrated above, some people like to use the indentation to call out specific aspects of the code. That may be "incorrect" from Python perspective, but it is a way of visually providing additional information that is not available to you if you use a language that requires a specific indenting style.
