For now I don't think we need to worry much about HKG and DEL as DL do not flight these routes from NYC so their code share with VS is a great fit. In fact DL do not fly anywhere in India.
If they were to offer a NYC-HKG codeshare with their sky team partners it would require a second stop which is a deal breaker for most flyers.
(AA offer a non stop via CX and UA flies directly)
