No. Enough readers asked for it. We had about five times as many complaints as we had positive comments when we went oversize A4. We thought it was a good move, those who really matter thought it wasn't.
Yes, there are slight savings, but resizing every template negates around two years' worth of anything saved, plus it's a pain in the arse to do, but the readers wanted it, so they got it. It really is that simple.
