Depends on what you mean by deny. If you are generating access-lists
from RAdb entries, obviously you will only be accepting those routes.
Unless you were doing as_path based filtering, you are implicitly 
filtering those other routes. Manually adding unregistered routes would
alleviate this problem until you had convinced them it was in their
interest to register.

It's not like you won't be able to peer with anyone after a certain 
date, but there are important reasons to register. 

-If you are multihomed, your upstreams will have synchronized access-lists
  allowing you more control over the shape of your traffic. 
-Convenient automated, synchronized and *authenticated* updates to your peers. 
-Portable central source for customer and local routing information. 
-Making IPMA/Merit/CAIDA projects more accurate. 

Am I correct in thinking that ANS and CAnet both require registration 
of their customers routes?

I'm sure that a site that used RtConfig for generating access-lists
would only do so for customers that had assured the site that their
registrations were current and worthy of production. Otherwise, 
routes are added manually.
