This should let getTypeName() and serialization work even when deserialization factories haven't been registered. I've made getTypeName() pure virtual like getFactory(), and moved all the overrides into SK_FLATTENABLE_HOOKS, cleaning up all the various ways we've done it before. All the subclasses override getTypeName() and getFactory() privately, so there should be no need to document them?
