That CRH is simple is a bit like claiming that MPLS is simple just because the header has few fields.
I think you would be hard pressed to substantiate that any solution here is particularly simpler than any other. But you are welcome to try.

Everyone claims to want a simple solution, funnily enough the end result is usually the opposite. The words "simple" and "source routing" are oxymorons.
Let's leave the marketing out of this.
