Shouldn't steam engines "save" their spinning direction?

unloading chunks (e.g. by quitting minecraft) will leave mechanisms such as steam engines in potentially weird states. stopping pumps cause updates and the weird state let steam engines start in random directions which lead to shafts being subjected to opposite rotations, which causes them to break.
