I used to be on the same page as the author. But then I saw tons of application teams not setting CPU limits, and coming to rely on the bursting (in other words, their requests were too low). Thus when the system came under load their application started slowing in unexpected ways.

We've had success with CPU limits, and horizontal scaling.
