I'm not sure how your serialization library works or is intended to 
work. But at some point you need a static type to be able to do 
something with the deserialized data.

In my serialization [1] it's possible (de)serialize any types without 
registering them. The only exception is when serializing an object 
through a base class reference, then the subclass(es) need to be registered.
