There are 3 cases where rolling through or jump starting at a red light makes sense, and is sometimes safer in my opinion. The first is a t-intersection where the bike lane runs through the non-traffic side - its absolutely safe to run these if you've verified nobody is in the crosswalk. The second is fast moving roads with no or shared bike lanes. In this case I find safely rolling through allows me to get ahead of traffic and up to speed before cars start flying by. I feel this is safer than impeding traffic as you clip in and more slowly get up to speed. Finally, red lights with pressure sensors and no upcoming cars to trigger them. Unless you want to sit there all day I think it's ok to roll through these.
