OK, if I must :-)
Authentication. A DC is not a cluster aware service. If a authenticated
application fails but the node does not, authentication can become
unpredictable.
DNS. A DC must point to a DDNS for it to work. Now you've added two semi DNS
servers that simply add complexity.
Scalability. Just read your Q article Q281662. Clustering other programs,
such as SQL or Exchange, in a scenario where the nodes are also domain
controllers, may not result in optimal performance due to resource
constraints.
Also from Q281662. You cannot cluster domain controllers for fault
tolerance. You can promote computers to be domain controllers, and then you
can install the Cluster service on those computers, but there is no method
to store Active Directory on any one of the cluster's managed drives. There
is no "failover" of Active Directory.
Also from Q281662. You may want to consider making cluster nodes domain
controllers (refer to article 171390 for more information), but if a domain
controller is already local, or there is a reliable high-speed connectivity
to a domain controller available, Microsoft does not recommend implementing
them on cluster nodes.
If you MUST, its one thing, just because you can is another.
