Description

This has been discussed for a couple of years now; perhaps with Abseil this could happen at some point:

https://github.com/protocolbuffers/protobuf/issues/1896

Using zero-copy proto parsing (which is standard practice inside Google, but not available in open source protocol buffers) would obviate the need for the zero-copy workaround that I'm going to implement for C++ Flight RPCs
