LH does this on their late night departures from India (~3:30am). Personally I like it; on the ~9hr flight from Bangalore or Mumbai to Frankfurt I want to get as much sleep as I can. FWIW Bangalore is served by the 3-class 748 and has less than stellar food options in the shared Plaza Premium lounge. Mumbai has much better lounge food options but are not what I would consider comparable to a Polaris lounge.
