I think before we assume this, someone should put some effort into describing the
rational for this. The meta-data in ZCatalog is a historical accident.  It's
real benefit is as an optimzation for search results, but I think it's worth
considering how important this optimization *really* is, before inventing yet-another
service to support it.
