Well, I think it is because so many people don't use version control in the intended way nowadays. I always review my changes before committing / pushing, but I have the impression many developers nowadays just stage, commit and push, as if VC is some sort of simple storage mechanism. I have talked to numerous people over the past few years to ask them to disable auto-formatting and/or to check their changes before pushing, but alas not always with the intended result. In the end I decided to push for using auto-formatting commit hooks in some projects (even though I dislike it on my own code).

An unfortunate observation: the majority of these projects were bloated, frontend javascript applications. In complicated backend applications I seem to encounter a higher SNR, and thus no necessity for commit-hooks.
