This sounds like handwaving to me.
It sounds like: "operators cannot get to agreement on what the real
and serious requirements are." And I then wonder....
what do the "SHOULD" requirements help us when developing the protocol
and solution? a "SHOULD allows people to NOT support or implement,
and so that may/will cause interoperability issues.
Specifically for INTER-AS (speifically if between multiple operators),
this is bound to cause interoperability problems.

That is rather a nagetive statement instead of a positive statement.
We must be clear in what is REQUIRED, not list a whole lot of "Would Be Nice"
things. If you want to list such "Would Be Nice" things in an appendic
and state clearly that they are just a wishlist... then I can live
with it. But now it is a mix of everything, which (in my view) will make
it more difficult when it is time to decide on the protocol/solution.
