While the text is certainly more informative, I'm not sure this is
a complete list of constraints, requirements, or goals.
So is this a list of considerations (which isn't necessarily complete), 
or is it a mixture of assumptions (such as multiple PA addresses being 
used)?

The draft-ietf-multi6-app-refer is a bit more nuanced than just "work 
unchanged". Based on what we know today, we can make unmodified 
applications work as long as all the address pairs are working, but in 
order for the referal-type cases to take advantage of all the address 
pairs, the applications doing referals either need to use FQDNs, or 
lists of addresses instead of a single address.
