The examinations of the code *that I have read so far* indicate 
that...?

Still leaving large organisations and smaller ISP's free to make
the decision themselves on whether the loss of Windows update
is more or less important than the prevention of the additional
spurious traffic.

In countries/situations where bandwidth is paid for by traffic 
transferred, and is often quite expensive, I suspect that more 
decisions will be made to eliminate access to WindowsUpdate, 
at least for a period of time, rather than paying for excess
traffic generated. 

It's more than a matter of degraded service.
