Hi Benjamin.
I don´t think this is an issue anymore.
You must have methods enougth to never need an extra query.
For example, I can´t imagine a situation where setProject is useful:
tipically you can set the foreign key between the project object and its
content objects in create() time. Assuming that contents of a project cannot
be moved to another project then setProject will never be used ergo it
doesn´t exists.
Sorry if I made an trivial interpretation of your question.
Thanks.
