Kind of disagree.

As a developer who works with code base that's got a git history going back over a decade and lot of legacy parts that haven't been touched in a long while, written by devs who've long since left, I fairly frequently wish they'd been more careful with the commit history.

You do mention project context as being relevant, but if bug fixes and refactoring _can_ be decoupled, it's a kindness to pull-request reviewers (if there are any) to do so and keep PRs small. It's also helpful if something needs to be rolled back if the commit history is fairly coherent.
