One clarification in the protocol I'd like to see is for the behavior when the X server time overflows to be clarified. Right now, Mutter simply uses the X server time to generate the millisecond part of high-precision timestamps when the overflow happens, so that is what X clients expect. I think the protocol should be clarified along those lines as well.
