There is a real problem with private naming, and that is that any use of 
private names that becomes successful is then faced with having to 
change all existing behaviors to move to a publicly-registered name.

I think it makes more sense to have new uses choose a name that can 
eventually be registered and simply experiment with it 'raw' until then. 
  Given the size of the namespace, the likelihood of a collision during 
initial testing is quite small.  To make it even smaller, we can make 
the barrier to getting an entry in the _Underscore registry very low.

1. What do you mean 'explain' and why should the registry contain this 
information?  Specifically, how is that information essential to simple 
and useful operation of the registry?

2. Entries of this type run the risk of either repeating text in the 
actual specification -- and therefore diverging from it if the spec 
changes -- or badly summarizing the spec.

I don't recall seeing any, in spite of how many _underscore names there 
already are.

Well, we know the concern about vanity use of DNS-related names is a 
long way from silly, so alas I guess we have to worry about that.  grrr...

 From the list of IANA choices for this:

      http://tools.ietf.org/html/rfc5226#section-4.2

I'm inclined to suggest 'Specification Required'.  In my own view, an 
internet draft ought to qualify, since they no longer disappear, but I 
believe the community view is that it would require an RFC or the like.
