There is only ONE component. So if you (or anyone) could please
send me a VEVENT that has TWO sequence numbers, one for the
old value and the other for the new instance that has changed.

I could see how a component could exist with TWO VEVENTS, one
with an EXDATE or EXRULE. The other with METHOD:ADD and the
new DTSTART. However BOTH would have changed, so both would
need sequence numbers, the old one with the new EXDATE/EXRULE,
and the new one.

But how could you ever show it on the wire if only one instance
had a new DTSTART, and the sequence number did not change?

I really do not see how one could ever be describe it in iCalendar
without the entire objects sequence number being changed.

Perhaps when I see how it would look on the wire I could agree.
