Why turn it off? Well, it is slightly annoying, no big deal, but I did read somewhere that continuous stopping/re-starting not ideal for the engine, don't remember the exact technical reasons.

I think there is a bit of misinformation going around regarding damaging the engine. Engine wear can occur with short journeys where the engine and probably more importantly, the oil is cold and has not circulated around the engine adequately.
As far as I'm aware the stop start function doesn't activate until the engine is up to temperature, so would have no effect on these potentially damaging short trips. Once up to temperature, stopping the engine for a minute or so at the lights would not reduce the temperature enough to cause any potential damage.
