If the package maintainers are correctly using the debconf priorities,
and the admin has chosen a debconf priority that accurately reflects
their preferences, why do you care?  By definition, any prompts at
priority medium or lower have reasonable defaults, so unless they're
shown to the admin *at his choice*, and the admin actively *chooses* a
non-default value, the configuration file won't be changed anyway.

Now, if there are questions being asked at priority high or higher that
have reasonable defaults, those are bugs.  I've had a few of these
myself, but no worries -- file and fix, and move on.  OTOH, if you're
running debconf with a priority preference of medium or lower... RTFM.

This claim is not reflected in our actual policy.  It's perfectly valid
for a maintainer script to make changes to non-conffile config file in
response to a user's expression of assent.
