Blocker Description
For serializing objects of types that are not supported by typed bytes serialization, applications might want to use a custom serialization format. Right now, typecode 0 has to be used for the bytes resulting from this custom serialization, which could lead to problems when deserializing the objects because the application cannot know if a byte sequence following typecode 0 is a customly serialized object or just a raw sequence of bytes. Therefore, a range of typecodes that are treated as aliases for 0 should be added, such that different typecodes can be used for application-specific purposes.
