I'm sorry -- I fail to see how "mental health issues" is an interesting version of this. For serious mental health issues (of the form of #1) we simply do not have reliable treatment options aside from involuntary confinement. For drug addiction the problem is more subtle but I question whether this part of the pipeline is worth considering when looking at the problem at scale. There is no serious attempt as far as I'm aware to measure the number of people that transition from #2 to #1 style homelessness, and since it is difficult to measure this it is very likely that solutions to #2 will have no effect on this pipeline.
