I have just file bug #588081, before finding that it was already
reported (with a misleading title, sorry), bugs merged.

No, this is completely wrong, for various reasons, the first being that

Which would be a minor/wishlist bug, yes.

And this is completely wrong, you should instead move them as explained
in the Debian wiki <http://wiki.debian.org/DpkgConffileHandling> or,
better, through dpkg-maintscript-helper (included in dpkg >= 220.127.116.11).

This is not the only drawback, *every* dpkg command will consider them
as conffile and even reportbug will include them, see bug #588081.

With the exception that dpkg will specially treat this (now) deleted
file. From the Debian Policy Manual, "Appendix E - Configuration file
handling (from old Packaging Manual)", "E.1 Automatic handling of
configuration files by dpkg":
When a package is installed for the first time dpkg will install the
file that comes with it, unless that would mean overwriting a file
already on the file system.
However, note that dpkg will not replace a conffile that was removed
by the user (or by a script). This is necessary because with some
programs a missing file produces an effect hard or impossible to
achieve in another way, so that a missing file needs to be kept that
way if the user did it.
Note that a package should not modify a dpkg-handled conffile in its
maintainer scripts. Doing this will lead to dpkg giving the user
confusing and possibly dangerous options for conffile update when the
package is upgraded.
In roundcube's postinst, you are exactly doing what you should not:
modifing a dpkg-handled conffile, bug severity raised to normal (not
serious because the Debian Policy extract above is a "should" and not a
"must" nor a "required").
