This is an excellent perspective. Those tradeoffs are often the root of these arguments anyway: Alice comes up with a solution that has some advantage x. Bob

This is an excellent perspective. Those tradeoffs are often the root of these arguments anyway: Alice comes up with a solution that has some advantage x. Bob comes up with a solution that has some advantage y. They'll argue endlessly because neither one of them will say "Oh you're right, I didn't consider x" or "I like your solution, but I don't know what's more important: x or y. Let's focus on determining that instead."
