"Relevance for compliance" setting on approval workflow step

Hello all,

I am trying to find out the purpose of the "Relevance for compliance" setting one can specify on approval workflow step (PWODecisionStep.ComplianceRelevance). Its possible values are "Not relevant" / "Information" / "Necessary measures".

But is there anything in out-of-the-box functionality really using it? By now I could not find the setting has any effect.

The version is 8.1.4.
