Possible future tutorial: Deploy Plasma with Ansible
By far the biggest blocker for this is the fact we do not have upstream Ansible modules for managing Plasma systems.
There are modules for both XFCE and GNOME for example.
Once we have an upstream module for, say, kwriteconfig/kreadconfig, we can have a tutorial dedicated to this in the System Administration section. For now this is just a suggestion for visibility and record.
