Status: OUT
Python's language defaults produce the quality inversion through a specific three-step causal chain: language features determine which strategies are self-sufficient, streaming is privileged because it requires no abstractions beyond what the language provides natively, and streaming's dominance is the specific mechanism through which algorithmic quality outpaces engineering quality — making the quality inversion a downstream consequence of language design rather than developer choice.
Language defaults determine strategy privilege (cause), streaming is the mechanism of quality inversion (effect) — combining them traces the quality inversion's full causal chain back to Python's design decisions.
