Love does sabotage my other values. I've made career sacrifices for it (which I don't regret).

Right. You do have to sacrifice some resources (time, mental energy, etc) that could be used for other things. All values do that, but some of them sabotage you more than just a reasonable resource cost.

Given complexity of value, most valuable things require tradeoffs. The difference between a bias and a value may be quantitative, but unless I know how to calculate it that doesn't help very much.

Sure it does. It helps us not be stupid about belief to know that belief is quantitative, likewise with many other things. It gives us the right mental model for thinking about it, even if we can't do actual calculations. That's why everyone is always talking about utility functions, even tho no one actually has access to one. Knowing that bias vs value is a spectrum helps us not get too concerned about placing them in hard categories.

Let's try to avoid sticking a "SOLVED" label on this problem before we've properly understood it.

This is a good point. "Solved" is a very serious label.
