MSP is surprising since DTW apparently didn't work at all as a HND route. It's probably the placeholder to be turned down.
Personally, I'd rather keep the nonstop NRT route than introduce HND at bad times and without onward DL intraAsiaconnections.
I guess DL is afraid to ask for SEA after losing the route due to inactivity not so long ago.
