Hm, I've always liked that behaviour, since it allows me to keep my local mirror thin (at 1-2 package revisions), while my cachedir contains older versions of only the packages I actually have/had installed. I realize this might be a bit "This breaks my workflow!", but I thought I'd at least bring it up :)
