What do you think about updating $ macro to support declaring the react-key attribute on a component?

(defnc habit-item
  [{::habit.model/keys [id name]}]
  {:helix/wrap [h/memo]
   :helix/key ::habit.model/id}
  (d/tr (d/th (pr-str id)) (d/th name)))

;; later in another component's render

(d/tbody
  (for [habit habit-list]
    ($ habit-item {:& habit})))

instead of having to pass the key:

(d/tbody
  (for [habit habit-list]
    ($ habit-item {:& habit :key (::habit.model/id habit)})))
