Perhaps not a phase-out program, but a progressive shut-down program, as a trade off between peak performance and total lifespan, where the characteristic patterns of ageing is what allowed humans to live much longer than other animals around the same size. Similar to the idea in this comic: https://www.badspacecomics.com/post/the-suit
By this logic, as a hedge against sudden death around ~50, the human body start cranking down the output of its diverse subsystems by then, to maximize operacional life, just like NASA engineers from time to time turn off instruments in the voyager to keep it operational against the odds. This is what we call ageing.
