Most of coding methodologies is about reducing the amount and the complexity of code that are written. And that's mostly why, on mature projects, most PRs (aside from refactoring) are tiny, because you're mostly refining an already existing model.

Writing code fast is never relevant to any tasks I've encountered. Instead it's mostly about fast editing (navigate quickly to the code I need to edit and efficiently modify it) and fast feedback (quick linting, compiling, and testing). That's the whole promise of IDEs, having a single dashboard for these.
