The scope of SR-MPLS is also "limited domain", because, quite obviously,
after 20 years, MPLS isn't yet end-to-end across the Internet, never was
designed to be and never will be.

So SPRING need to declare SR-MPLS deprecated first before the "limited
domain" argument can be attempted to be used against CRH.
