I found another problem with the default FSP rules in 184.108.40.206.0. The default dispersion rule use dRevClassID
The problem is that dRevClassID will change if you use Archiver to copy your content to another UCM instance. This is a common practice using a "Contribution - Consumption Model". Content is created and updated on a "Contribution" UCM instance and then Archiver is used to copy the content to a "Consumption" instance where it is viewed by users/consumers. If dRevClassID is used in the dispersion rule the webviewable URL will change when the content is copied from contribution to consumption. If you have any links to the content, say from a Site Studio site, they will not work on the consumption instance.
I talked to development about this and they said they realized the problem existed a while back and it will be addressed in the next patch set (220.127.116.11.0) by using dDocName instead of dRevClassID.
You may want to consider changing the dispersion rules in your system to match this if you are going to be using a contribution - consumption model
