Another important feature is stream-oriented caching of values. Essentially some range of opcodes in the stream language are reserved for referring to a cache of recently seen values. It's a "dynamic" encoding feature that's super beneficial for common payloads, like JSON API responses with lots of similar keys. This is something a protobuf/thrift-like should steal, as it can often be more efficient than vanilla field-number + value encoding.
