IMHO if we want some new behavior/policy there should be a new corresponding
property, not desktop/server. That can be quite misleading and I would
rather see it go away. Other than use it as a set of default values
Sure, let's call it something else, but this is a typical behavior expected from the
desktop/server property. So what we are going to do is that remove the property and throw
away all the related data, while when (if ever) we get the new property (behaveAsDesktop,
notUsedWhenNotConnected, whatever we call it) the users of the system will set this
property for the VM's that used to be desktops. We could save that work for the
users.
Also, it may appear to be an edge-case, but for a good scheduling in my opinion this is
important.
