It's great CBOR is accepted in wider area, but I am personally curious why WebAuthn choose CBOR instead of JSON. WebAuthn is a web browser feature, and why W3C would introduce a new data exchange format in their specs? Maybe WebAuthn needed a binary data type?

I'm guessing a binary format is nice when interacting with a device..

Anybody know if (and why) U2F uses CBOR?
