Hygiene Management?

I’m installing Exchange 2010 and in the docs it shows a bunch of groups that get created in the AD Schema during the domain prep part. After running prep, I looked to see if the groups were there, and sure enough they were (yay). What caught my eye was that one of the groups is called Hygiene Management. I thought maybe this was an Easter Egg from MS, but apparently it’s just the name of the group of people who can manage the Exchange antivirus/antispam features. Still funny though.
