> SCION right now provides the backbone for the Swiss financial network moving 200 billion CHF each day

This is a meaningless benchmark - for a small group of trusted big enterprises with insurance policies and mutually signed contracts you could've just as well used OSPF with zero filters.

The benchmark would be adoption by an actual large number of parties that don't/can't talk to eachother spread across the world. With a large chunk of them being malicious or incompetent to the point of being effectively malicious.

I'm not claiming that this shows SCION can replace the respective parts of the network stack right now, and you're right that at a global scale this is still an unproven technology. But I would argue that a technology needs a certain level of matureness / is not "snake oil" if it is deployed in a heavily regulated and comparatively conservative sector such as banking.
