It's a worthwhile precaution, but there's no way to demonstrate how much it contributes to resistor longevity. These failures happen so infrequently, it's just as likely to be within normal manufacturing tolerance. Everything has a failure rate. Jules has said that 0.3% or so of his resistors fail, so it's pretty rare. So, when it does happen it attracts a lot of attention and invites various theories about the cause.
I'm more concerned about the lack of fuse protection. It's obvious that the 80amp fusible link in the motor supply circuit isn't doing what it should.
