In fact, M4 can also be *nothing*. In other words, it may be optional. This is precisely because, from one block to the next, we have constrained D2 such that it is only allowed to change in a few ways. Therefore, the exhaustive set of "candidate D2s" can be precomputed by full nodes in advance. In fact, M4 can also be *nothing*. In other words, it may be optional.
