I believe that you believe that.
Based on my ~38 years of IETF experience, and having personal experience with
network engineering for a multi-continent broadband ISP, I disagree with your
characterization.

This is a minor, almost trivial, extension to very well-understood Traffic
Engineering (TE) mechanisms. Further, I disagree that this proposal narrowly
fits “one design/architecture” and disagree that any uninterested operator
would need to upgrade anything.

Operators that choose to use the mechanism are perfectly capable of making
their own cost/benefit analyses. Further, the operators I’ve spoken with
disagree with the claim that any “massive almost network wide upgrade” would be
required.
