See the reddit post explaining a lot here: https://reddit.com/r/linux/comments/1dpeqay/config_vtn_in_20...

Coming to a distro near you, probably!

Is this just for the looks? Or is there any other benefit here?

There's no Virtual Terminal, aka TTY / VT, so the kernel is smaller and the insecure VT impl in the Kernel is not compiled in. In general, you get less moving parts and a more solid system.

The functionality of the VT as a fallback can be handled by cage+foot/whatever or kmscon.
