Not docker specific, but there are still lots and lots of servers out there running multiple services. Especially in my home-lab! Each service runs under a service-specific user, sometimes with extra hardening applied by systemd. It's a tried-and-true method for gaining some semblance of security boundaries on a shared server without the additional administration overhead of kubernetes or similar. A more relevant use case to industry might be a CI machine that you want to get better utilization out of. Easy, just start of multiple CI runners under different users. "Just use Kubernetes" I hear someone screaming? Well, sometimes you need CI on macOS.
