I mean, if you treat commits as a line in changelog and write them that way, then the difference in outputs between autogenerated changelog and what you're talking pretty much goes away. CC style can easily be enforced automatically, I often just rewrite commit messages when merging PRs from contributors, so it looks nice when I run git-cliff on it. You can always add a pre-face by hand to what was generated for every release.
