The better you understand the reasons behind the rules, the easier it will be to know when to break them.
Or, in an artistic sense, how best to dramatically or subtly break them in service to some creative perspective.
Any of them! All of them!
This is as true in architecture, rocket design, fashion and etiquette, as it is in prose.

And this is why organizations that impose process without delegating and encouraging an organization-wide agency to make intentional exceptions, smother innovation so effectively.
They lose most of their creative and adaptive abilities.
None of these are meant to be "rules" in my understanding. The post starts with "In most instances", so it leaves plenty of room for "exceptions" to the list based on what you intend to convey.
