Doctor Who Confidential cancelled

As reported by The Guardian, Doctor Who Confidential, the behind-the-scenes companion program to Doctor Who, will not be returning with the next series, as part of the BBC's cost cutting. The BBC had this to say on the matter:

Doctor Who Confidential has been a great show for BBC3 over the years but our priority now is to build on original British commissions, unique to the channel.

I can't deny Confidential is far from perfect; it's too long, so gets padded out with fluff. But both excuses given by the BBC seem flawed to me: It must be one of the cheapest programs they can make, as everything they need for it is already in place from the production of Doctor Who; all they have to do is throw an extra crew in to film it, and pop it through an edit suite. And it is an original British commission, or is documentary exempt from that classification? What other program gives viewers such an incite in television production? An inspirational and informative look at one of the UK's biggest industries. It seems to me that the BBC should be the proud home of such programing, not removing it for poor reasons.
