I prefer: <short description> <BLANK LINE> <Detailed information> <BLANK LINE> <footer>

Using a type is to contrived, because your commit will often include e.g documentation and a feature. Splitting them for the sake of following this pattern makes no sense.

You can actually specify multiple types in one go usually.

The actual purpose is mostly for tooling to help generate release notes.
