We will make this as a new deprecation rule guideline:
When a rule with broad scope exist but has possibly many FPs and that a rule with a smaller scope fully included in the broad rule exists and has no FP, the rule with the small scope should not be deprecated. We accept the duplicate.
At least we would like to provide to the user some recommendation in the rule documentation indicating to fix the rule with smaller scope first. Ideally the issue on the broader scope should be hidden to the user.
