Is there a reason why DropdownMenu takes an expanded parameter, but something like AlertDialog does not? What kind of requirements / constraints go into deciding whether a composable should have such a parameter?

The dropdown menu does animation when going from expanded to not, so it needs to be called even when not expanded.

AlertDialog don't have animation, so to show or hide you just call or not call the function.
