That is not the point here. We are not discussing whether or not nirodha samapatti is liberation. We are discussing when nirodha is used in some contexts like "saññā-vedayita-nirodha", if appeasement is the best translation. Imo, non-arising is the best in that context.
You asked about our thoughts on the translation "appeasement". but as Dave said, sometimes the word nirodha is best translated as non-arising
