Yeah, that's a common user interface issue.

Now that we have mandatory bits, though, this could be solved by a simple
protocol extension: allow routes to carry a "subdomain tag", and allow
filtering on the subdomain tag.  So in Rome you say

  redistribute ip ::/0 subdomain-tag rome
  in subdomain-tag rome allow
  in subdomain-tag "" allow
  in deny

and any routes tagged with Athens are dropped without any confusing
network prefixes in your config file.

Please expand on that.
