No argument there. The Toyota 5S-FE non-interference engine is a near indestructible 4 cylinder engine that's well documented, popular and you can purchase parts for pennies. It has powered 10 models of Camrys and Lexus and battle proven. You can expect any mechanic who has been a professional mechanic for the last 3 years know exactly what to do when it starts acting up. 1 out of 4 cars on the road have this engine or a close clone of it.
It's not what any reasonable person would use for a weedwhacker, lawnmower, pool pump or an air compressor.
Sure, but to extend your metaphor, Kubernetes HAS smaller engine models that you can use in those situations, and still gain all the benefits of being in the same ecosystem. You can use K3s, for example, and get all the benefits without having a giant engine in your weedwhacker.
