Why discuss non-alternatives? (Was Re: DTSTART for recurrence instances)

I will soon be out of touch for a few weeks on vacation so I may not be 
able to continue this discussion until I get back.  Fore warning in case 
it appears as if I just disappeared (my silence is not acceptance, merely 
my inability to participate while traveling)

Actually they all represent ways for an Organizer to recreate a 3 instance 
repeat set.  Since there is a fundamental difference between a simple 
instance reschedule (iTIP Section 3.2.2.1 Rescheduling an Event) and 
recreating all instances in the repeat set (see the analysis from 
yesterday), why are we even considering these "alternatives"? 

If the intent of this discussion is how to determine how RECURRENCE-IDs 
are assigned in the CS then thats simple to answer (see iCalendar). 

If the intent of this discussion is to understand how 
invitation/rescheduling of a repeating instance happens then thats also 
simple to answer (see iTIP). 

However it seems that the intent is to discuss alternative means of trying 
to represent an instance reschedule (which are not truely equivalent) for 
reasons that I just dont grok.

Why do we spend cycles discussing different means of recreating the entire 
repeating set (as opposed to actually rescheduling the just that instance) 
which have no direct bearing on how the EXPAND property is handled on a 
query?

What steps of the C&S workflow process are not already documented in iTIP? 
 

Also, I am having a hard time understanding how any of this digression 
relates to handling EXPAND on a query.  Am I the only one?
