Isn't that kind of the default position for these types of builds? Nobody wants to be the team that built a thing that died on day 101 when the mission was designed for 100 days. Everyone wants the science to stop not because the platform stopped working but because bean counters shut it down. Everyone wants to be the team that built Curiosity long outliving its mission duration while continuing to do science. Otherwise, the bids will go to the teams that build Voyagers or Curiosity and never come to the team that builds systems that last exactly mission duration

Maybe nobody in the science world. But in the commercial world, it's the requirement so it's not a bug it's a feature.
