I think the general idea we settled on is that we specify an earliest display time for each frame and give feedback to the application when a frame was actually displayed.
That is indeed something completely different, and feels like it would be several years in the future, while the proposed scheme or the min/max properties could be done fairly quickly. But I'm not in a hurry.
X11 already supports that with the DRI3 extension. Also see VDPAU present and the Vulkan extension for reference application API implementations, so that stuff is already present.
I suspect you mean the Present extension, specifically PresentOptionUST. There is no working implementation of this yet (the xserver tree has never had any code which would even advertise PresentCapabilityUST, let alone do anything with a timestamp passed in by the client).
