This is exactly how the internet works today and you just don’t see it. Try using source routing in your IP packets and see how far it gets. BGP implementations had to carry a “work with Cisco’s bug” flag for decades. Send some >1500 MTU packets across the world with varying paths and see how fragmentation and assembly is inconsistent across operators and implementations. RFCs are loaded with errata, they skimp on critical details, and have bullshit “design by committee” features that never panned out. They aren’t special.
