Disagree. Well, maybe still acceptable if the software is small / limited to a single paper. Having worked on a code base the people writing it learned programming on that job, guessing their intention is like archeology. And each iteration tended to add some complicated interdependence. Or like when int errorCode came from other, overlapping error ranges.

A part of the "new" code base is exactly as described by TFA. Including most interfaces having only one implementation. But while annoying, I am more able to work on it without things breaking...
