To clarify, are you saying Connected Networks with ULA-Only (NPTv6 & 
ALP) section 4.2.1 deployment models are harmful?

I agree with this, with the caveat we have to acknowledge these exist in 
order to call them harmful.  I've heard in the past that some what them 
removed completely.  I prefer to keep them and call them harmful.

Or are you saying all ULA deployment models are harmful?  If you are 
saying this I need to better understand what you mean and way you think 
this.

Thanks.
