This is a great point.

At a micro level, this helps articulate why rewriting/refactoring a feature just after writing the first version of it is so quick, relatively. And why it is often easier to write better code in a second pass. The first time you had to build the theory AND the code at the same time. In subsequent passes, you have the benefit of the theory from the start.

I think this concept is self-evident to most experienced engineers, but I have not heard quite as succinct an articulation of it before.
