So should soldered CPU always be judged for repairability too? It's also the same repairability/efficiency tradeoff against using socketed (desktop) CPU instead.
Maybe designing a computer with 10/10 repairability and 10/10 power efficiency isn't possible. That doesn't mean we should dilute either of those metrics to make it look that way.
A repairability score should reflect that tradeoff, not excuse it.
