Depends what you have in mind, I guess. You could run most essential system components (syslog, ssh, cron...) inside containers, and bind-mount /home when it makes sense. Since those components need elevated privileges, I don't know if containers would be that useful... And then systemd already puts services in cgroups; it's a nice approach (IMHO). Or you could use containers a bit like virtualenvs. If you're a Python developer familiar with virtualenvwrapper, you probably use mkvirtualenv when you start working on a new project (or on a different setup for an existing project). Containers could be used in a similar manner with some clever wrappers.
