Component comprehensions - LiveComponent docs uses the legacy syntax, do they need to be updated?

The function component documentation mentions that it can use the new syntax:

<.error :for={msg <- @errors} message={msg}/>

The LiveComponent documentation uses the legacy syntax:

<%= for card <- @cards do %>
  <.live_component module={CardComponent} card={card} id={} board_id={@id} />
<% end %>

Is this a case of documentation needing to be updated or is do LiveComponents just not support the new syntax?
