It is almost certain that any file in `/etc' that is in your package's
filesystem archive should be listed in dpkg's `conffiles' control area
file. (See the *Debian Packaging Manual*).

If a conffile is not a configuration file in some cases,
please point me to the file. I contend that a conffile is merely a
user modifiable configuration file; I think you are nitpicking at
subtle semantics here.
I think not. We can ask for a policy clarification here, but
as I recall the policy discussion, the intent was never to subvert
the section 3.3.7 by naming a configuration fine as a conf file and
bypassing the whole section.

The point being?

So? conffiles are obviously a subset of all possible
configutration files. This is a configuration file that is created by
and manipulated by the postinst, and therefore does not exist in the
package itself, and hence does not need to be a conf file.

This I disagree with.

So what? what are postinst files for? Which games need a
binary high scores file? why can't they put the scores file in /etc
and make a pointer to it? Maintainer laziness is no excuse to not
enforce policy. Ask for a /etc/games if required, but I think that
the games that expect an existent score file are few, and they can be
handled with a symbolic link.

Look further in section 3.3.7, my proposal is merely a
modification of the dor file and /etc/skel proposal.

Oh, I do not think so. just moving user modifiable
configuration files shall not significantly increase the size of
/etc. Just look at the sizes of the violators; and compare them to
the size of /etc. I have looked at the numbvers. have you?
