Well, it didn't take long for this thread to reach the point of 
diminishing returns.

FWIW, my take on it is the following.

The document should not be considered to be an update to 4271, as it 
does not change anything 4271 says, and does not update or extend the 
protocol in any way.  Standards track seems entirely inappropriate, as 
there is no protocol specification in it.

The document is not really a Best Current Practices document, as it 
advocates a change from current practice.

The document is okay as an Informational document representing the 
consensus of the GROW WG.  It would be nice if the document indicated 
that it only considers the use of BGP when providing Internet service, 
and does not consider other uses of BGP.  It would also be nice if the 
document indicated that there may be unintended side-effects of changing 
the defaults, but the authors consider those to be of no consequence.
