The RNext notes uses iCalendar model were RECURRENCE-ID's never change. This will not change unless there is a VERY good argument to do so.
So if SEQUENCE:1 changes 100% of all instances. Then SEQUENCE:2 trying to cancel one of the new (SEQUENCE:1 instances.
You can't becaues you would have no idea what was being canceled if the RECURRENCE-ID refer to the SEQUENCE:0 instances.
