Thanks for bringing this back for another last call.


I think that the approach documented in this document is a fine solution for
a somewhat limited SFC deployment. It has the benefits of using existing
techniques and tools, and satisfies the need for a quick deployment solution
for SFC.


I am not convinced that this solution is scalable to complex chains or large
networks with very many chains, but that is not the point. We have other
solutions (as Andy notes) for those problems. Those other solutions may also
be more generic and widely applicable, ultimately covering the problem space
addressed by this draft, but that is not the point either.


Furthermore, as this solution is already shipping (if I understand various
claims correctly), it is worthwhile publishing.


The current version seems "good enough".
