We cannot guarantee that no file on disk is owned by the user or group.
The local admin may for instance have made a backup copy of files owned
by the user (cp -a /etc/foo/ /etc/foo.bak;  suppose something in that
dir is uid or gid user).  After purging the package they are still there
and after installing another daemon they are suddenly owned by another
package's user.
