Currently the item level emitter can handle the state of some itemstack or a crafting task, but also the stored ae amount in a network. Which currently does not match the fluid one missing the energy part.

An alternative would be to also support it with the fluid one, but that would still be an inconsistency with level emitters from addons as we have no control over them to also add this functionality.

Further it might expose this functionality itself better as actual part and not hidden behind a toggle button.
