I have been going through Active Directory book and found out that once you enable recycle bin in your domain you do no need to have an infrastructure master (IM) FSMO role required even if the DC is not a global catalog.
The reason is no where to be found, what exactly is the reason once you enable the recycle bin you no longer use IM, does Recycle bin starts to act like IM that is taking care of phantom objects.
I would appreciate to help me with some TechNet article if available.
