I think this is an overstatement.
If there is conflict between the documentation and the implementation, I
rather change the documentation. Unless it is clearly a bug.
Rationale: Changing the behaviour of something might break existing
application (remember we pretend to maintain binary compatibility).
While a change to the documentation won't break anyone's code.

It should. But that implies the documentation is pefrectly written.

I like to know what is under the hood when i am writing my own code. It helps
to understand the performence penalty, and also the corenr case.
For example, we don't document the complexity of every function.
