Should they have to meet basically the same criteria as a Internet 
connected assignments them?

To maybe help develop a consensus, could you expand on why you think 
this is a bad idea?

Are you suggestion we should do both #1 and #3?  It kind of seems to me 
that you are, and I hadn't thought of that option.  I think I hear you 
saying there are three types of network in question;

1. Internet Connected
2. Non-Connected
3. Never to be Connected

And, never to be connected networks should be served by ULA or 
ULA-Central, and that filtering them is probably OK.  But, that 
non-connected networks should be served out of 2000::/3 and that making 
them easy to filter them is not OK.

This is an interesting idea I need to think about more.
