Yes, I had the same thought...

It would be, and indeed, that is similar to what the final patch does. The problem is that it requires an extra allocation (we do not want to unconditionally put the object_context into the object_array because it is too big, so we add only a pointer). So having rev_info->pending store that information would mean that callers would have to know to free it when freeing the pending array. We would have to either teach each existing caller to do so, or perhaps enable the behavior only when a certain flag is set (e.g., rev->keep_object_context or something).
