What is the point?  We want to move to the actual state as soon as we
can, where as soon is defined by a backend.  So we need manual control
over exact states, including change state.

Even for testing it makes much more sense to have entirely manual
control, so that your userspace test framework can trivial inject too
long transition faults.
