Is there a debian/ubuntu policy on softlinking things to another location in opt once they're installed properly in usr/share or usr/lib?

Here's a simple example: Packaging up dnsenum. It's a REALLY simple package (4 files).
A perl script, two wordlists, and a readme.

So from what I gather:
The wordlists should go in usr/share/dnsenum/*
The perl script itself would go in usr/lib/dnsenum/
The readme would go in usr/share/doc/dnsenum/

Add a wrapper bash script that goes in bin and just passes arguments to dnsenum.pl.

The question is this:

If there are various tools that provide wordlists or some other shared resource, is there a policy on linking all the wordlists from different packages in to /opt/wordlists/ ?

It seems like the "right" thing to do respecting the directory structure while still making things convenient.
