Prematurely in your mind, perhaps, but not necessarily from your employer's point of view. The earlier you die, the quicker any benefits you might still be receiving, vested or otherwise, will stop. If you don't live to retirement age, it will not be a problem to replace you for less, either through hiring an H-1B Visa holder or by exporting the work.
