Really? Why? All CS's have RSS feeds, this just puts the link tag in on every page in the CS. Every page already has the "RSS Feeds" link, but that's not as handy for setting a Live Bookmark in Mozilla, for example.
The CS seems to put this link tag in regardless of whether or not the Enable RSS property is set to Yes or No, which may be a bug. But currently, I'm just duplicating that functionality.
I don't think this needs to be optional, it's almost a bug fix.
