As someone who uses these lights on a daily basis as a pedestrian I can confirm that something has definately happened to them in the last few weeks as they are now very pedestrian friendly. There used to be a good minute wait upon pressing the button, at the moment they are stopping traffic without any one pressing the button. Great for my morning walk to the station, not so good when I'm driving past. I'm guessing this can be easily fixed if TFL pay attention to your email.
