	Not really. Why do we need this overly micromanaging rule in
 policy? As long as it understood that user data is not to be deleted,
 why can't I put user data in /var/lib/<pkg>/ if I so desire, as long
 as I take care to not rm -rf that dir?

	If you don't want files in category 5 to be deleted as a
 matter of policy, fine, then say so. Creating braod rules that have a
 secondary effect of doing what you want accomplished, but also
 restrict other scenarios, is bad.  No package should be forced to
 create a second directory somewhere.
