Forefront Client Security release notes and best practices

I noticed this post over at the Forefront Client Security blog asking for feedback from customers that use the same management group name for multiple deployments within the same environment.

As a best practice they recommend using different management group names for each deployment. There are many other interesting issues documented within the FCS release notes too.

I am curious why this is a best practice because they don't really explain the reason behind it.
I suspect due to avoiding 'reporting stampedes' from FCS clients to only one management group, but I'm not sure overall.
