Yes, I recommend to take a similar policy to database packages :

- rrd & meta-data (/var/lib/munin/**) should be treated like DB data :
only removed "manually"
- munin & plugin configuration (/etc/munin/**) should be treated like
DB engine config : removed on "purge"
- plugin states (/var/lib/munin-node/plugin-state/**) should also be
treated like DB engine config : removed on "purge"
- anything else should be treated like DB engine : removed on "remove".

The idea is to avoid removing data that has a value, and data that
remains should remains usable (ie: with its metadata).

Removing plugin state should not be automatic, but not retained at all
costs, as one expects a "clean" reinstall after purge, specially on a
node.
