No, if anything, it makes even less sense. If all the daemons are running as root, then the excuse that was put forward, that using shadow would stop the necessary daemons from being able to perform their synchronisation properly, is moot.
In the situation I am talking about here, root is often not used as a super-user. Although it would be understood that in the requirement of XCP this might be bypassed, the easy-access by keeping the password in a world-readable file would not be acceptable.
