Carsten, I’m not following with this.

dCBOR is justified by use cases like those Wolf, Christopher and myself have described. dCBOR as a justification to create and validate application profiles seems circular because so far dCBOR is the only application profile described.

The simple question is: independent of application profiles, are there are enough compelling use cases to justify WG adoption of dCBOR?

Similarly, whether or not we standardize application profiles should rest on there being enough use cases to justify it.
