Exactly. screen/tmux aren't on the same "slippery slope". Asking for screen/tmux isn't like asking for vim. It's a meta-feature for managing your containers themselves. 

In fact, adding screen or tmux would make using containers to extend functionality easier, so in the long run it makes it less likely for people to ask for other features/utilities. It decreases the angle of the slippery slope.

On extending the vulnerabilty surface: I certainly appreciate that adding tmux/screen is also adding potential CVE's. However, let's be real. If we were to prioritize feature addition by likelihood of security issues... Atomic wouldn't have Docker. :)
