All this body of work along with a whole lot of discussion and brainstorming happening in the Spring WG provided the architecture, use-cases, applicability and requirements for SRH (RFC8754).

Continuing with your analogy, it would seem to me that in the process, 
Net-PGM decided to break the roads and ditch traffic rules so that their 
"new" vehicle could run faster, while ignoring that other folks and 
vehicles need those very same roads to be safe and reliable.
