The extension of the timeline is, to me, not a very positive thing. I've been recommending for some time now that the government produce the information, the statistical data, on a quarterly basis in an open and reusable format.
I use these statistics quite a lot, and they assist everyone in holding the government to account in its performance. What happens now is that in the spring we usually get these statistics trickling in, and this typically continues until September. September is also the projected extension of the timeline, which is very late in the day, because that's performance reporting on the previous year.
