It would be in Indias interest to destroy pakistani offensive capabilities in at least one of its military arm (Navy>Air Force>Army).
Pak Navy is the easiest to pick out now but we can't guarantee the same in a decade once they have their new ships arrive from China and Turkey. They won't eclipse us all of a sudden but definitely more of a headache then they are currently are.
Taking out the Navy will give us the additional advantage of controlling their coasts and entry of ships, their Air Force will be stretched thin to compensate for security at the coast.
Pak Should not be allowed to have a Navy ever again.
