Here is the non-RFC version of of my proposed protocol transition plan which can be found here: https://public-inbox.org/git/20170824225328.8174-1-bmw...@google.com/
The main take away from the comments on the RFC were that the first transition shouldn't be drastic, so this patch set introduces protocol v1 which is simply protocol v0 (which is what I'm calling the current git wire protocol) with a single pkt-line containing a version string before the ref advertisement. I have included tests for protocol version 1 to verify that it works with the following transports: git://, file://, ssh://, and http://. I have also included an interop test to ensure that sending the version request out of band doesn't cause issues with older servers. Any and all comments and feedback are welcome, thanks!
