Claude in general probably increases observed bugs in rsync, because it can churn out vulnerability reports that necessitate tons of changes to software that people are accustomed to working flawlessly in non-pathological use cases.

I don't have empirical evidence for this claim, but best I can tell, security patches are the principal source of observed bugs in software of a certain vintage, because they cause churn. (Just think of Windows updates that break drivers.)
