Refresh patterns and ACLs

One of the things that came up in Sydney briefly was whether the stale-
while-revalidate and max-stale refresh_pattern options would be better
expressed as ACLs.

Taking this a bit further, could/should the same be true of the rest
of the refresh_pattern options (and perhaps of the patterns themselves)?

E.g., I have a user who wants to ignore-reload selectively based upon
client IP; surely a good fit for an ACL if there ever were one...

Just food for thought,
