The word "successive" implies a time dimension already. I'm not sure
what you are proposing here.

No I haven't considered this second requirement. It would be
interesting to note whether it is a derivative concept (can be derived
from the standard QM principles say), or whether it needs to be added
in as a fundamental requirement (in which case comes the question of
why).
