Should I care about removing watcher after a component did unmount?

Let's say I have following component with a local state and some watching logic:

(defn some-component []
  (r/with-let [local-state (r/atom {...})
               _ (add-watch local-state :on-change handle-change)]
    [:div ...]))

Should I care about removing the watcher (if yes, what's a best way to do that), or it will happen automatically when the component does unmount.
