Any wire protocol or syntax changes?

I can't seem to find a "things we want to do in wire protocol v4" doc in
the wiki but I know I've seen occasional discussion of things that can't
be done without protocol changes. Anyone with a better memory than me
able to pitch in?

What'd be required to support in-band query cancellation? Sending
per-statement GUCs (to allow true statement timeout)?

I can't think of any major syntax warts and grandfathered quirks that'd
be really great to get rid of if we had the freedom to break things.
