Anyway, there are many more cases where dpkg -L does not list all files
pertaining to a single package. Configuration files managed by
postinsts, for example, instances data, etc.
It's a shame there is no standard way to declare the (package-)ownership
of a file (the cruft(1) format is good enough, but is under-used, to say
the least).
I have recently taken an interest in obsolete conffiles and it's a real
mess to check whether a conffile is really obsolete (can be removed) or
is now managed by postinst (or ucf). Some conffiles left behind can have
side-effects (usually not important ones).
