I also don't agree with what you are saying concerning the maintenance of the GCs.
If you only have 1 domain in the forest there is NO OVERHEAD in making all DCs GCs. The size of your DIT will not grow in size because there are no other domains. For its own and single domain the GCs will use pointers to the domain data. So if you have 1 domain, make all DCs GCs. Even if you have multiple domains there as less issues in W2K3 compared to W2K because W2K3 DCs/GCs use Linked Value Replication (only in FFL w2k3) and for the partial attribute set it only replicates the deltas. So even for a multiple domain forest I would consider making all DCs GCs. Concerning exchange I would not manually define the DCs and GCs it uses. Let exchange itself figure that out. What are the reasons to manually define the DCs/GCs it uses?
