When updating a collection from one side to another, how do you determine which item to update? If the collection is indexed and you're happy with that indexing (e.g. list position) then you might want to go that way. In many cases, you'll want to use persistent Ids, but in some cases even that won't be sufficient (e.g. saving repeatedly from a client that is unaware of the persistent ids).

In any case, the user needs to be able to control which object is considered equal with custom code.
