      fwiw, the reason Ember is so pushy about computed properties is to avoid your #3.

      Back when two-way binding was popular computed properties seems like another confusing layer

      #3 would be better if cWRP had a more reduce-y API where you return a value. Then it would be more obvious how to compose it.

      It's nicer to pull values when you need them than to reduce eagerly into one value, I think.

          At this point I think the most important thing is consistency: however you do it all of the app works that way (mixing them = worst of both)

          Wait I thought cWRP *just* to help interop w/ 3rd party, non-react utilities? Isn't manually updating state from props in cWRP anti-pattern?

          I don't think so. If you use `setState`, that depends on props, you have to. Forbidding that makes apps even uglier imho

          Updating state based on props (not very common but happens) is the only supported use case for cWRP

          But shouldn't that state be derived and pulled in render()?

          But then you don't need the hook at all

          It's useful, rarely, when processing the props is CPU-intensive. Can happen in certain situations

          If the value you pull is made by heavy computation. otherwise it doesn't really matter
