I guess my sense is that most biological systems are going to be ‘package deals’ instead of ‘cleanly separable’ as much as possible—if you already have a system that’s doing learning, and you can tweak that system in order to get something that gets you some of the benefits of a VoI framework (without actually calculating VoI), I expect biology to do that.
I agree about the general principle, even if I don’t think this particular thing is an example because of the “not maximizing sum of future rewards” thing.
