No the concern is the 2 cases where we are asked to create and return an
entity given only an id. This happens in 2 cases:
* In response to Session#load / EntityManager#getReference
* When building a non-eager "to-one" association reference, which is really
a specialization of the first case

After a quick look, one of key points is
Loader#doQueryAndInitializeNonLazyCollections?
This is the point where the entities get loaded and properties set during
the load from database?
