Is that relevant? I think the point is that ignition has been demonstrated. That gives people confidence that it is possible and can only accelerate research.
That thermonuclear ignition can be technologically achieved has, unfortunately, already been demonstrated. It has not yet been demonstrated in a way that seems to be leading to practical power production, and that goes for this result, too.
Lawrence Livermore director Kim Budil is being misleading in saying that this is necessary first step. Ignition will be a necessary step along the path to practical fusion power generation (if it can be achieved), but it is far from clear that inertial fusion is on that path.
