> 3. It should not be redundant

Not sure I agree with this one. While abstractions are a great way to reduce the length of code, sometimes they break readability. When you read code, sometimes, you feel like you don't read a solution to your problem, but a way to solve your problem masked behind abstractions far removed from the domain concepts.

That's why, sometimes, redundancy is better than the wrong abstraction.

I've seen some very good arguments about 'redundancy' that's actually the same lines of code performing a different function in different places. In this case, naive de-duplication just adds unnecessary interdependencies between otherwise unrelated parts of the codebase.
