Hi,

> 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.

As a user I usually find:
Fewer fields -> fewer moving bits -> simpler to understand and debug

> 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.

It is indeed all more complex than simple SRC->DST routing.

Cheers,
Sander
