Yeah even further, does that mean that SAAS like S3 shouldn't exist because it has multiple users? I guess one possible solve would be to separate shared services into separate private deployments. Every upstream service gets its own imagine hosting service. Updates can roll out independently. I guess that would solve the blast radius/single source of failure problems but that seems really extreme.
