Functions 200-300+ LOC reduce cognitive overhead by surfacing important logic visually; empirical evidence shows bug rates per line favor larger functions over fragmented small ones.

Summary
Stops cargo-culting Clean Code dogma that fragments critical business logic across dozens of micro-functions, making modules harder to navigate and debug in practice.

Implementation verdict
Replaces reflexive function-splitting with intentional hierarchy: crux functions (200-300 LOC), support functions (10-20 LOC), utilities (5-10 LOC). Requires discipline to distinguish necessity from dogma. Worth adopting now if your team debugs by reading, not by following call stacks.
