Yeah, I would agree that something simple probably should have been included.
The reasoning here is that this allows people to use protocol buffers with
whatever other systems they might already be using (eg. HTTP, databases, files,
RPC protocols, whatever), without being tied to a specific implementation.
Compare the protocol buffer API to Thrift, for example, where the message
serialization/deserialization is tied pretty tightly to the RPC system. There
were proposals to possibly add a "protocol buffer utils" API, or a "streaming"
API, but neither of those went anywhere. The closest thing is writeDelimitedTo
/ mergeDelimitedFrom in the Java API:
