True, It is not nescesarily a problem. Depends on where you store it,
and keep in mind that if you're doing session clustering, the whole
list would have to be serialized too, while this is not the case for
detachable models. Also, by using detachable models, you can avoid
having problems with e.g. lazy loading relations in Hibernate (for
which you need the current session, which is closed after your current
session, etc). The /advantage/ of plain lists is that they are easier
to work with, and if they don't change much, that's more efficiently
than re-getting them all the time.
