The package installs a symbolic link and a file with the same name in both /sbin/ and /usr/sbin/, so it makes impossible to convert a system to the everything-in-usr directories scheme.
It's still broken in the current version: $ dpkg -c davfs2_1.5.2-1.1_amd64.deb | grep ^l.*/usr lrwxrwxrwx root/root 0 2016-01-06 17:32 ./sbin/umount.davfs -> /usr/sbin/umount.davfs lrwxrwxrwx root/root 0 2016-01-06 17:32 ./sbin/mount.davfs -> /usr/sbin/mount.davfs -- Jakub Wilk
