I found this enlightening, in that I'd never really understood the point of deliberate destructive uploading until now.

A preference report in return: I would strongly prefer P1 over P2, mildly prefer P2 & P1 over just P1, and moderately prefer P2 over nothing (call nothing P0). I think of destructive-upload as death, but I think I value the algorithm I'm running somewhat, even in the absence of the hardware currently running it.

Given the opportunity to do a non-destructive upload, I would certainly take it. Given the opportunity to do a destructive upload, I would....well, I might take it anyway. Not because it wouldn't be death, but because not taking it would eventually result in P0. I would prefer such an upload to take place as late in life as possible, assuming the possibility of early death by accident is ignored. (I am not certain which way I would go if it was not ignored)
