I propose that we add assign_new_async that follows the same conventions as assign_new.
My use case is a live_component that assigns some data with assign_async based on its assigns in its update callback. But I don’t want to do it every time that the component is rerendered, only on the initial load.
If it is something the maintainers wants, I will gladly take a stab at it, trying to follow the logic of assign_new.
