You're assuming a level of engineering/scientific "purity" that doesn't really exist within orgs to the idealistic extent that we would like to imagine. I'm not saying that I'm smarter than every FAANG engineer, but having met quite a few and worked in large orgs myself, it's easy to say some of these tools come from pride/arrogance/a need to have your name on something/a fundamental misunderstanding of existing tooling. Not necessarily because they're unraveling parts of the universe yet unexplored and need a bespoke weapon to tackle new issues.
