in a general sense, i think yes.

i think this is mostly correct.  in the CatalogMultiplex scenario, 
however, you have multiple catalogs, and different content types 
registered with one or more of them.  in this case we'd still need to 
preserve somewhere this catalog:type registry mapping.  also, while it 
would be possible to have each catalog as an event listener, checking 
the registry to see if (un)indexing is appropriate, it would be more 
efficient to have the registry itself being the listener, delegating 
only to the appropriate catalogs based on the type of object being 
manipulated.
