Stop/ Start is actually more common on diesels. Eg Renault Kangoo and Fiat Doblo have S/S on their diesels, but it's not an option on petrol versions. I think all Euro diesels across the board have it, no doubt because they're all very close to various emissions limits.

I have S/S on my Trafic and while it's early days, I don't seem to be getting a lot of DPF regen cycles. Sitting and idling doesn't do a DPF any good either, the EGT's are low and so it's just filling with soot, it may well be better to stop the engine. Of course, S/S is inhibited during a DPF regen.
