Yeah but sometimes you do get meaningless changes that aren't just whitespace even with auto formatters. For example if you change the indentation on some code and that causes it to wrap an expression.

The solution to the whitespace gripe is strictly enforced formatting standards with a git hook running a manually invokable script.

Throwing a linter into the pipeline just hardcodes the formatting at that point in the pipeline. That doesn't really solve the issue, which is that style is not a one-size-fits-all concept, and displaying text appropriately is really the job of a text editor. To quote PEP 8, "default wrapping in most tools disrupts the visual structure of the code". In other words, "most tools" suck at displaying code, because they are not language-aware. That's the real problem. Hardcoding style is a workaround, not a solution.

That said, I wouldn't consider intelligent editors to be a replacement for formatting standards, either. Ideally my text editor would display my Python code the way I like it, and then save to disk in accordance to PEP 8.
