This is an interesting use case, and I don't have a good solution. Do
you have any suggestions for how this replacement might be represented
in JMAP? Happy to consider something, and whether any added complexity
is worth the benefit. I can see this could also be useful in the draft
case being discussed, for other clients to know which draft replaced a
previous one.
