Active Directory Recycle Bin and Infrastructure FSMO Role.

Question

Hello!
In the book about Active Directory I have found the information:
"Once the Active Directory Recycle Bin has been enabled, the infrastructure master’s functions are performed independently by every DC in the forest. That is, the tasks just described are no longer delegated to a single DC."
I have looked for additional information and found only one article from trusted source:  http://msdn.microsoft.com/en-us/library/cc223753.aspx :
"When the Recycle Bin optional feature is enabled, every DC is responsible for updating its cross-domain object references in the event that the referenced object is moved, renamed, or deleted. In this case, there are no tasks associated with the Infrastructure
FSMO role, and it is not important which domain controller owns the Infrastructure Master role."
Someone have any additional information about this changes?
How Infrastructure Master role works, after enabling AD Recycle bin?

Answer 1

From my understanding is that the Infrastructure Role ceases to do the updating when cross-domain objects are moved-renamed- deleted and now becomes the function of the domain controller that did the action. This makes the role of Infrastructure Master redundant
thus no longer a necessary role.
When you enable the Recycle Bin - that's a forest wide operation meaning that each domain must be at least a windows 2008 R2 domain level and the forest is a 2008 R2 level -
