I consider packages over 100k download production-tested. Sure LLM can roll some by themselves but if many edge cases to appear, (which may already be handled by public packages) you will need to handle it.
Don't base anything on just download numbers, not only is it easily game-able, it's enough with like 3 small companies using a package and push commits individually and CI triggering on every new commit for that number to lose any sort of meaning.
Vanity metrics should not be used for engineering decisions.
