@iwanowww Thanks for the comments!

I'm still not 100% happy with it. It really feels like we are introducing some tech-debt here. What should the next person do who also needs to attach something else to the SafePoint? It is also easy to miss places where we have to special case the extra edges. I don't have a solution here, I'm just not extremely satisfied. Is there a better long-term solution?
