But this discussion is focused on modifying conffiles from *other* packages.
(package B modifies package A's conffiles).  Is there some means by which a
conffile from another package can be deregistered as a conffile?

I suppose the package that plans on modifying it could deregister it and make a
backup on configure, and then reregister it and restore the backup on purge.
