Being a terminal purist is wonderful for those of us who live our lives deep in the caverns of Linux, but in actual production use you very often find situations where less technical users have to interact with the systems that we build.

For my work, I need a way for low level tech support and technicians to go in and restart a container from time to time, and these people curl up in a ball and scream if you show them a command prompt. Having a UI removes a lot of friction.
