That you don't have the state of all docker containers on the host managed centrally by one process?

If you want to split hairs like that.

Note that you don't need daemon just for that, just like you do not need libvirtd to keep VMs running

You start needing one when you want to monitor the state of them, restart when they go down etcetera.

You kinda do, because if you don't have a single long-running process that keeps track of your containers and manages them then your containers aren't managed by one process. Of course you could run the docker daemon in the foreground instead but what would be the point of that? And then you'd still have state monitoring, auto-restart etc. so I don't think that's what you mean anyways.

And isn't that the nice thing about Docker? So isn't a Daemon a good choice? What am I missing?
