To reiterate, I am also against changing the version ID. However, I do think 
it's worth updating the context string version number, otherwise it'd be a 
little unnecessarily confusing there. (trivial change to key derivation, but 
not wire format) I've also made a point to tweak references to the on-the-wire 
version value to refer to it as a "version ID" rather than just version, to 
make it very clear that this is really just an arbitrary codepoint and 
shouldn't be read as 3.4.

I've made the changes for a WIP branch, here (not a PR, as of yet):
https://github.com/tlswg/tls13-spec/compare/master...davegarrett:tls2rebranding

Going through the motions of doing the renaming now is useful to see if there's 
anything that is more affected than initially expected, such as the context 
strings having the version in there directly as a string (they're designed to 
be updated as-needed, so this shouldn't be a problem).
