Bug? "Page Cache > Cache feeds" doesnt cache RSS Feeds

I notice your “Cache feeds” under Page Cache doesnt cache the rss feed pages at all. Although i have it checkmarked it seems to ignore rss feeds but does cache the other things (e.g. tags). I would expect in your cache directory for the site you would make a “feed” directory to store the page caches. Nope. Nothing. There was also nothing created in any other directory.

Is this a bug in W3T?
