Don't think of them as kill lanes. Think of them as harass and denial lanes. Kills should be fourth on your priority list at all times when you play support. First is letting your partner cs safely, second is keeping yourself alive, and third is causing problems for the people you're laning against.

Letting your partner cs safely consists of causing big enough problems for the people you're laning against that they focus their harass on you and not your partner, or pushing them out of lane all together.

The only time kills should cross your mind is when your jungler comes down, or if your harass gets them low enough and they don't b for whatever reason.

Kill lanes are essentially what non-support players try to do when they get stuck with support. It's for people who don't enjoy or don't understand (or both) what support is. Mainly people who think support is a baby sitting roll.
