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.
