Probably won't get anyone killed, but I've seen loss of data. Valuable data. And now you're going to point to the disclaimer and 321 backups...

Websites are seen by everyone seeking not a site, but a feature, via search engines. Same as a poster if you look in that direction.

Why are you trusting data to some random open-source project with no documentation?

The search engine is only going to direct you to my open source repo if you're searching for whatever it does. It's as if you'd only see my cake recipe if you were searching for cake recipes. And just like cake recipes, your search results will contain everything from superb production-tested projects (if there are any) to random stuff people have put up that isn't really used.

If you're searching for software and you find some random project that isn't very well tested or maintained, and you put that project to use in a place where it can cause data loss, that again sounds like a you problem.
