Of course I agree with this. We should fight undue complexity at every step. This beast tends to creep up very quickly and we're all guilty of it at times. This is indeed particularly obvious in otherwise rich languages like C++ or Rust. Those tend to push people to try to be clever and show off, often for "performance reasons". This is rarely a good idea, think twice.

I would have titled the "defer refactoring" section differently though. Probably "defer abstracting" would have fit the bill better.
