Les,

 
> The statement “the … Prefix SID does NOT have the semantics that we want and causes deleterious side-effects” is FALSE.


Ahem.  I disagree.  No need to be rude about it.


> There is an alternative here:
>  
> Given that there isn’t any defined use case for the Area Prefix/SID, you could choose to defer its definition until such time as a use case arises.
> I agree that the concept is appealing and is potentially useful – which is why I thought it worthwhile to invest time in defining it. But a conservative approach might be to wait until we actually need it before defining it. It is always possible that when the use case arises we will find that there are some other issues which have been overlooked which might alter how this would be advertised.


You’ve heard two of our customers here on the list tell you that they want this.  Therefore, we’re going to ship it.
