logind can be used to know the list of existing user sessions and which
have console access, it also creates and to some extent manages cgroups
but it doesn't do anything that the device namespace would at the kernel
level.

The main benefit from having a device namespace in the kernel would be
to only get the uevents and device access for devices that are either
owned or shared with the container. Being able to have fake devices
replace some of the standard ones would also be nice to have.
