 I know that the general consensus is that a post should be assigned to a
 single category and have many tags.  However, we ALLOW a user to set as
 many categories as they want and I'm constantly facing customers that use
 multiple categories and are frustrated that they can't set a "preferred"
 category for their permalinks.  The category in the permalink is simply
 determined by the lowest ID with this code:
 {{{
 usort($cats, '_usort_terms_by_ID');
 }}}

 If we add a filter just after that, or better yet change it to a filter
 and add the usort USING the filter, then a plugin could use business logic
 to decide what category belongs in the permalink instead of being forced
 to use one that may make no sense.
