I've had the same reaction. In fact it's not all non-collections, but some
kinds of objects that can be deserialized without the lib needing to
construct anything :

When an object is deserialized explictly by the user, she provides a
constructed object to the serialization lib.
If this object is a container of some sort (or is a pointer, or holds
pointers, etc..), sub-objects  might have to be constructed by the
deserialization code.  
If it's not the case, all constructions have already been done, and the lib
just calls deserialization functions on constructed objects (conceptually,
they are the exception, and collections fall into the more general
category)
