speaking as an explorer, if i build a ship which i take out for several weeks or months, i will try to build a ship which allows me to explore that fancy landable around a carbon star, which i might find, or anything i'm not even thinking off.
exploration builds are pretty much builds preparing for the unexpected, for extremes.
you can go to beagle point and back with out ever needing a heatsink. but you can also hit one of those trinaries, which let you wish for having a heat sink fitted. etc. pp.
i'm just thinking your nice research would be better by presenting the whole context, and not "sharpening" it by hyperboles as quoted above ("The ONLY exception is in purely silent running builds"). it generally helps presenting the facts.
