I think the general idea we settled on is that we specify an earliest

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).
