I'm sure that you can find many ways in which there are a lot of broken 
packages in Debian or in any other distribution.  That said if we have a 
strong precedent in Debian for doing things a certain way it is an argument 
for doing more of the same.

https://en.wikipedia.org/wiki/Filesystem_Hierarchy_Standard

# State information. Persistent data modified by programs as they run, e.g.,
# databases, packaging system metadata, etc.

The above section from the above URL suggests that package maintained files 
aren't suitable.

The description of /usr is:
# Secondary hierarchy for read-only user data; contains the majority of
# (multi-)user utilities and applications.

For /usr/share it says:
# Architecture-independent (shared) data.

I think that /usr/share is the best place for it.  If /var/lib has symlinks 
into /usr/share then files which aren't changed can be replaced by a package 
upgrade while files that are modified by utilities can stay modified.
