This article is not aimed at people who are working in a codebase where everything is super terrible. It's written for performance aware programming. One of the aspects of performance awareness is awareness of how virtual functions and tiny functions affect performance negatively.

> Also articles like this usually fail to mention code maintenance cost. For example by reducing usage of virtual calls you can make your code unmaintainable/expandable and suddenly every new change will cost you 2x more in development time.

This never actually happens in real life. I've never seen a codebase that is written with "clean code" principles in mind that is also maintainable and easy to develop on top of.
