I disagree with a couple statements here.
1) A jet engine at idle IS producing thrust - just less thrust than you might like. It is NOT causing drag, as a windmilling, shut-down engine does.
2) Whether it "requires" the OEI checklist is a matter of SOP. Our SOP (4-engine airplane) did not. Whether it is smart to refer to that checklist is another matter. Yes, it is a good idea to refresh your memory on what is impacted. You still have the associated generator, hydraulic pumps, and bleed air; you have reverse idle available on landing. You will need significantly less rudder input than if the engine was shut down. Your performance will be somewhat better than if it was shut down. Depending on the runway, flap limitations in the OEI checklist may or may not be prudent.
