Me too.

No.  It is still a domain name in the sense that it is within the universe of 
identifiers under a singly rooted namespace used on the public Internet (the 
"domain name namespace").  What it is not is a part of the subset of that 
namespace that is resolved using the DNS protocol/infrastructure.

They are bad precedents because of the challenges they caused for network 
operations. Specifically, the fact that they were local policy considerations 
meant that references to a .bitnet or .uucp name within one administrative 
domain would work but would fail when that reference escaped that 
administrative domain (e.g., in a cc line of an email address). In my view, 
this is essentially the same problem that led to the IAB publishing 2826. One 
of my concerns with 6761 is that it can encourage recreating that operationally 
challenging world without explaining the inherent risks.

I disagree. I believe the domain name namespace can be broken down into:

1. In the DNS (exists within the root zone)
2. Not in the DNS (exists within the special use registry)
3. Not defined (everything else)

The primary issue I have with 6761 is that while it is relatively clear who the 
authority is for (1) and (2), it does not provide a clear answer about the 
authority for (3) or how a name gets put into (1) or (2) when taken in the 
context of 2860, section 4.3.

Which is, of course, one of the key problems. It results in an undefined 
decision process dependent on the individual subjective evaluation of IESG 
members.  Given the economic, political, and social implications of the naming 
hairball, this seems like a really bad idea to me.
