Hi Nick

The goal of RFC  9098 from a IPv6 operations and security perspective is to
shed light on the issues surrounding all extension headers generalization
as due to the pervasive  Christmas tree issue with excessive header
chaining to issues related to processing of headers in the slow path.

Out of all the headers the one and only that has been historically the most
problematic is HBH and has resulted in operators filtering HBH to avoid
possible DDOS attack vector.

This draft hones in on HBH as it is the most problematic but it is also one
of the most useful for developers to build tools for operators toolbox.

This document also provides  a path forward to make HBH usable and it’s
viability for future development of new features that can be extremely
beneficial to  the internet community.

Kind Regards

Gyan
