It would have to be something that doesn't wrap, I think, or the only
significant advantage I can see (being tied to the timeline instead
of "free running time") is lost.

Dito. I'm (actually) trying to figure out what I missed, so I'm
definitely interested in finding out. (If I don't know why I'm
implementing a feature, how the h*ll am I going to get it right...?)
As far as I can tell, you can always ask the host to convert
timestamps between any formats you like. If you absolutely cannot
accept pluigns implementing qeueing of events after the end of the
buffer time frame, the host could provide "long time queueing" - with
whatever timestamp format you like. (All we need is room for some 64
bits for timestamps - and events have to be 32 bytes anyway.)
But, when is musical time in ordinary events *required*?
