To try to make it clearer that the application can't express this type
of preferences for the destination addresses.

Do you have a list handy?
=> it seems that someone should reread RFC 3484 very carefully.
I'll try to do it if I get enough free time...

Any concerns about where and when the failures due to lack of
an address satisfying the REQUIREs?
=> EADDRNOTAVAIL on bind(), connect(), sendto(), etc. (i.e.,
all system calls which directly or indirectly assign a source address).

I don't understand what you are suggesting to change in the document
with respect to this.
Care to elaborate?
=> I disagree only about the rationale, so I propose to remove the statement
which begins by "Note".
