Great point. I've found that most codebases have some abstractions that work very well and others that work less well, and simply having awareness of this can help make the code far more readable. For instance, one might say: "The way x is implemented works, but it's not quite the right abstraction, here's why". That is way more informative than saying it's simply the wrong abstraction or considering it good enough and ignoring its deficiencies.
