Yes, I've seen that advertised as the whole point of having OODBMSes: the database would act as a more or less transparent object model "persister". (Just like XML databases, which persist XML documents.) This implies a pretty drastic change to the nature of the relationship between database and application, but I'm not convinced it's always bad to do things that way.
Moreover, an OODBMS doesn't force you to omit step 3.
