I think this is required for future extension of this feature wherein
I think there could be multiple such xids say when we support parallel
apply workers. I think if we get a good way to do it even after the
first version like by making a xid an optional parameter.
Extending the behavior is doable, and maybe we end up without this limitation in the future, so be it. But I’m having a hard time imagining a scenario where the xid is not already known to the system, and the user, and wants to be in effect for a very short window.
